Failure P0091 Fiat Bravo 1.9 150 HP

[bravosport150]

Guys I have a FIAT BRAVO SPORT 150 HP NO DPF with downpipe.
Let me explain: I made one that is rimappature, a map for my car, was lucky? the map on my car and as soon as you load the map we tested the machine and to the first accelerated deep in 4th gear, and? in engine failure, with fiat ecu scan gave us error on the high pressure pump (P0091), then the mapper I get up a little bit the limiter of the rail from 4% to 5%, the riprovammo and not gave us the most? the error, and then I paid him ? gone via.
Here it is, after just a month ? re-presented, in acceleration I by engine failure, I was going about 120Km/h in sixth gear on the 2100rpm about, I started to accelerate deeply for overtaking and bhammm error and the machine plant is not pushing the pi? as it should, and going to failure....I stop for a few minutes and then allocation should be well again....
The error ? the P0091 - fuel Pressure regulator (Inlet of the high pressure pump).

After a while the ricontattai and I reimpost? the pressure of the rail on the original and then at 1600, I tried the machine again and in third gear sank the accelerator and as soon as you start? to push here come again the engine failure.
Here is the preparer told me that it could depend from the pump, from the high pressure sensor on the pump or from the sensor rail, then armed with patience I bought the sensor rail and the original regulator high pressure on the pump and I have changed both, but guess what....you ? resubmitted the same error.


I contacted a dear friend of mine and he gave me a map that I uploaded but ? repeated the error again.

I have to say that the preparer asked, a little, what? a maximum of 20 or 25Cv and the car I consume less leisurely pace.

Now, I would like to understand from you what could be in reality? a matter of the map, or mechanical?
I'm attaching some of the maps (in addition to the original) that I have loaded and that all I have to the failure. Just today, my friend gave me yet another map (the 6 that you can find in the archive which I enclose) with the section of rail set to the original and told me to try it.

For those who want to view the maps he send me a pm that I'll give you the password for the archive

__________________________________________________ ________________________________________________

Guys finally today I was able to make the diagnosis active, I'm armed with notebook and I was able to bring up the damage, as you can see in the graph, corresponding to each peak of the deal? of diesel oil demand (chart below), the opening of the pressure regulator is lower (chart above), I have surrounded of red where are you ? verified the failure, in fact, as you can see the pressure regulator ? went to zero....in the previous cases, as I told you it was open but did not ? got to zero.
I also noticed that the opening of the pressure regulator does not exceed the 48,92%, but according to you ? normal? The Cio? that regulator should get to 100%, or maximum reaches 50%?

What the hell can? be according to you....is driving me crazy this thing. It is as if when it needs more? diesel or pressure, or how you want to define, the regulator lowers until you get to zero in some cases and let me go the machine in recovery! sad.gif

The other thing I noticed ? that pressure diesel measured exceeds the goal set by the map, the cio? if on the map the maximum pressure should be 1664bar I've seen that the measured till even 1687bar, cos? as you can see in the maximum and minimum values on the left of the image. The limiter in this map? ? set also 1664bar cos? as the maximum pressure, but really? nothing was happening....If for? notice the point where I had the failure, the pressure of the fuel measured ? remained the most? low of the goal....

Guys what and how could I solve it? It would be more? indicated to bring the car to a pompista?
Thanks in advance :)

[bravosport150]

I has already? answered Tidus elsewhere for? today I ? came this doubt:
and if it was the fault of the injector?

I did these tests with the machine stopped in neutral, the first screen ? made with the engine at a minimum while the second screen with the engine led to about 1650 rpm.

What do you think of those fixes that backs?

To any of you ? success?

[progress]

hello first of all, in order to remove the doubt if it's a problem of the map do is replace the file ori and then try again if anything goes wrong then the problem and the mechanical/electrical if it was the opposite of the problem lies in the map,and here come into play the guru of the mappings that after I posted the mod file will tell you or advise where the problem lies and how to solve it

[legendaryslave]

you have to make a what to monitor the pressure of the objective and the measured and also low so you can see what is lacking in ps with the map ori the same thing happens

[msport (exil77grande)]

I would like if possible that inserissi files ori and mod without a pass,if you need advice we are here, but with the pass does not make sense.

[blackwolf76]

I ? capitanto several times that those cars do that type of problem, acceleration, maximum and random, or it turns off or goes into protection, then start again like nothing had happened.
In this case the ideal thing to do ? to upload a map ori only luca stanca, now that you have not more?, then try again if the problem reoccurs. If it were to happen again exclude a mapping problem, then you need to revise or replace the high pressure pump, which at the 99% ? the culprit, considering that you have already replaced the pressure regulator (subject to breakage), and you could save yourself the sensor, which does not break almost never.

[bravosport150]

the guys with the map ori, not me ? seemed to have the failure, but again can? be that being the original chiss? what circumstances must be present to permit? to appear the breakdown, boooo
Guys I attach the map files without a password.

What do you think of these corrections on the injectors?

[bravosport150]

you have to make a what to monitor the pressure of the objective and the measured and also low so you can see what is lacking in ps with the map ori the same thing happens

this is a test I made and you can see in the first picture that I posted above (the one with the graph), where it is reported the pressure of the diesel oil objective and measured, When you press that measured out just over the goal, the cio? in that map the goal was 1664bar and I got to 1687bar, cos? as you will notice to the left of the image, so a little deviation there is, but I think it might be normal right?

not was good, however, to disassemble the float in the tank and see if ? clogged of dirt you have to exclude a fall in the low monitoring the pressure , once you've established that in the circuit ? everything is ok" eye to the valve on the filter", however, known that in the time skip furi the error missing 300 millibars you are powerless are the internal valves of the pump that can hold more pressure

[bravosport150]

ok these days will change? the diesel fuel filter and will prove? the pump in the tank is clean.
You in the time of the failure of a no-pressure, but the strange thing ? that he does not always, in fact if you see the chart in the previous moments, those pressures have reached safely, as ever? Should always do that no-pressure?

[motorsport]

hello,a pompista definitely find the defect,the problem and the mechanical part!!

[bravosport150]

yes, now I have to try the map, then change fuel filter and clean the pump, the low pressure in the tank and then continues to the right from a pompista.

Guys what do you think of those corrections made from the injectors? You may also center the injectors?

[msport (exil77grande)]

I have analyzed some of the maps you posted it seems to me that there are 2 different hands, but those that I have seen, even if not all, maybe not the top, but I don't think they can give you problems, so from my point of view to test the map with rail pressure ori and if it does still put the file ori and the door from the pompista.

[bravosport150]

there are 3 different hands....but with all gave me the problem! :(

Guys what do you think of those corrections made from the injectors? You may also center the injectors?

[SandroMarciano]

when the correction should be over 2mm^3/s) sure are not going well, look at how much fixes a cold, just turned on, but before you control the system from the point of view of the pump. one of the injectors, if anything ? a secondary problem, but at that ****llo't manage to send in the failure of the machine.

[bravosport150]

ahh ok, but at least I have those values while if I accelerate, and I'm about 1600giri (in the second image), changing values and falling?

[SandroMarciano]

to this question it might take a few paginated post for the answer to that... grossly depends on the fluid dynamics of the fuel that is sprayed on, which in turn depends on pressure, loss of charge that you can have different capacities and fequenze different.

[bravosport150]

Guys I would like to buy this additive Bardahl http://www.bardahl.it/lubrificanti_additivi/olio_motore/auto/additivi_motore_auto/additivi_diesel/pulitore_iniettori_diesel.html#2 but according to you, how should I use it?
On the instructions it says to pour it in the tank with about 20 gallons of diesel, while I was on my old car having a diesel filter with the hole above, the versavo inside of the fuel filter again, filling it with the cleaner, I mounted the filter and turned on, while on the filter of my Bravo does not c'? the hole in the argo where you can pour the cleaner, but there are the two usual tubes.
What do you advise me?

[blackwolf76]

Do not waste money on additives and rebuild the master rail.

[bravosport150]

you're right, but as sedo to change the filter before I take it to a pompista, I would like to use this cleaner for the injectors ;)

[SandroMarciano]

the injectors are not dirty but off by as much, and this often happens when you put the petrol in the tank.

[alfajtd]

the injectors are not dirty but off by as much, and this often happens when you put the petrol in the tank.

if you put the petrol in the tank is not starano, ruin definitely risking that then do not put it in the bike..
you have to immediately provide for the review and taking it from pompista that value? the damage... it does not exclude the pump HP is ruined..

[bravosport150]

azzz I never mass of the petrol, but I know that some people just to clean the injectors on the full put 10€ of gasoline, quiandi at this point are making a big mistake right?
Sorry, but these cleaners bardahl are good or bad?

[alfajtd]

? a wrong thing to do....
for? on the different that go to the gas by mistake....

to clean the injectors take a workshop with a dedicated device without removing the injectors
you do the cleaning while the engine idles...

I was on my do it every 2 years or when I notice that it runs clean... you can taste the difference... do not use additives in the middle...
and always from the same fuel distributor except in exceptional cases...

[bravosport150]

ahh I get it, how is it done this cleaning without removing the injectors?
But you do in the day?

[alfajtd]

ahh I get it, how is it done this cleaning without removing the injectors?
But you do in the day?

To me, they do it with the tool of wins, about an hour..
Stick to the flow...

[bravosport150]

ahh, behold, good to know.

[tt225]

To me, they do it with the tool of wins, about an hour..
Stick to the flow...

I confirm it works well

[bravosport150]

guys a question if in FES, I carry out the procedure where it says: replace the ecu and the injectors, what happens?
Why? today I tried but after the first step I cancelled...what might happen?

[blackwolf76]

I don't think anything happen to serious... maybe doing an adaptation poratta, but it certainly does not solve anything if the problem ? to ****llo mechanical.

[rego88]

hello.... where are you? I solved a problem last week on a 159, had a map light, and as it sank zac... the problem was.... where are you?? he wants us to disassemble the pump dell high pressure.... and as for the corrections of the injectors at 90% resolve by adding the additive to the fuel injectors and with the reset of the parameters autoadattativi inside the engine control unit.....

[bravosport150]

I am pugliese and you?
I did not understand what this phrase means: he wants us to disassemble the pump dell high-pressure

[rego88]

the problem lies in the high-pressure pump.... must be disassembled and show it to a pompista bravo... you to solve the problem.... but to turn the pump to the tour you have to disassemble the machine, I'm in the marche.... a little lontanucci!!

[paolo159]

You have irregularities at a minimum for the case? If you hot or cold?
Unfortunately I can not yet see the attachments...having the map I could give a hand... 2mm of correction are altini but there might be something to check in the map.
if you can send me the map in pvt I give him a look...I already had your same problem and I resolved, therefore, does not harm to try

[msport (exil77grande)]

thank you for your availability, but if you read the rules you know very well that we can send you the file in pm.

[bravosport150]

the guys here there are two schools of thought, those who say that it depends on the map and who says that ? the high pressure pump, now I'm trying a new map...let's see how it goes and I'll know.

[paolo159]

*msport:
I'm sorry, but I didn't know not to ask for the file...I have not read the regulations clearly..
Thanks for the information anyway :-)

*bravosport150: if I were you before taking the car out of the pompista from which surely spend I would try to load the map ori, and verification that the anomaly is not present so? you can understand where is the problem... not try other map mod that does not make much sense in this case.
If the ori the car is fine you can rule out problems with the pump and look for the anomaly on the map.

[carmageddon]

if the car goes well with the original file, does not always mean that the problem was triggered by the modified file, or better, the modified file may induce error, but simply because? some body or the sensor are at the end of life.

[bravosport150]

[paolo159]

*carmageddon: you are right but you have to go for exclusion then in my opinion it from what is pi? simple, and then put the map ori, then to the pu? proceed with further testing..

*bravosport150: make a good analysis with the original map and do the data log you will see that if you actually c'? something wrong with the mechanics you see...once you make the log e-mail well graphics, as well as you did in the first post, looking perhaps to reproduce the same situation in which you had the problem.
Then a good cleaning of the filter, diesel certainly doesn't hurt ;-)

[bravosport150]

no the fuel filter I have to just change I'm taking the one in the new UFI ;)

[motorsport]

if you can do all the tests with filter and map, and not solve, if you need to rebuild the pump hp let me know they are available!!! :)

[bravosport150]

but I see that you are in the campania region :(

[motorsport]

What the problem??? is to disassemble the pump from your mechanic and the ship...I think with a modest price it is worth,the first currency and let me know....

[bravosport150]

Then I have to pay both you and the mechanic to disassemble and reassemble it, and at this point I would prefer to do to a person.
But you will have happened to other cars with the same error and problem, and there was something in the high pressure pump, which was not?

[paolo159]

bravosport150 where are you from?

[bravosport150]

I am pugliese

[carmageddon]

but it would be way too long and I do not have

make a diagnosis or to find solutions through the web ? never easy, if not impossible, in spite of all you ingegnino in various solutions.
the fact ? that ? need to get the car to visit with cognition, knowledge, and patience...the answer that you wrote above ? the kind of risporta that should never be written because? I would say so? : let's see when you walk or you will grow tired of flaw if you can't find the time to take it to someone who knows what to do!

each request has its own working time, fast things, and you can only do that by only if you know them...no offense eh!

[bravosport150]

[danny677]

Sorry but your a good pump premandata to be there ? if you, it could simply be that she does not bring enough oil to the main pump by making it go into the block as soon as the request of nafta ? high.. I happened to have several of the common rail cos

[bravosport150]

are you referring to the pump in the tank?

[danny677]

it could be spompa

[bravosport150]

but with multiecuscan can I do a test/test/active diagnosis to see if it works as it should the pump in the tank?

[danny677]

ecuscan I don't think but the examiner fiat surely.

[paolo159]

it also does multiecuscan, look in the section actuators (F6) - fuel pump relay.

to do the test, keep the car off, and in a quiet place, as you turn on the pump you will have to feel the tac of the relay, and a sort of slight whistle if the pump works

[danny677]

Ok, but the deviation of pressure in bar ( usually at least 3 ) you say ? It is obvious that the on/off even without the diagnosis, the experience - besides the fact that if off should not be in the bike :)

[bravosport150]

is the test on/off I have already? fact and feels the operation, but I was wondering if you could do an active diagnosis of pump pressure tank...can you? to do with MES?

[progress]

to see the pressure of the pump to dive you have to connect a pressure gauge on the tubes, at the entrance of the fuel filter, possibly, by the examiner multiecuscan see only the high pressure as a parameter

[bravosport150]

ahh, behold, now ? clear.

[danny677]

I would add that, if you are at least 3 bar, you can ensure that the diesel fuel needed to pump rail main otherwise would not know how to suck it to push it to the injectors and give them the right flow rate.

[bravosport150]

but the pump in the tank, once the machine ? on keeps a constant pressure of 3bar, or at the request of the high pressure pump she adjusts to what pressure to push the fuel?

[danny677]

that and a constant , the excess of course back to the tank

[bravosport150]

ok then just mount a pressure gauge, turn on the car and also from a stop and in neutral, see if the gauge is I marks 3bar constant, if it does, it means that the pump in the tank ? to exclude, right?

[danny677]

exact, but by some accelerated, if the pressure were to fall visibly means that the flow rate that the pump has very little.

[bravosport150]

ok make? this test...

[ecucilacunta]

I advise you to take the test with a pressure gauge on the road.

[bravosport150]

but why? it may also vary in acceleration?

[paolo159]

why? acceleration is the demand for a greater number? of fuel, and if the pump fails to meet the required prex caler

[bravosport150]

but you told me that it is in the crowds both in acceleration and the pump in the tank has a constant pressure of 3bar, then at this point ? true that ? constant, but varies according to the requests of the accelerator?

[mariodarkblue]

you were told wrong, the pump pressure of the tank ? ALWAYS 3 bars...then what ? the hp pump that raises the pressure according to the request dle engine!

[bravosport150]

then they told me the same thing that you say, what? that the pressure of the pump in the tank ? always 3 bar constant....right?

[blackwolf76]

I know that here you write a lot, and it concluede little.:cool:

If you do not start to do some test do not exit, even why? 100 people tell you 100 different things. You have to start from one side and go forward...

[motorsport]

I know that here you write a lot, and it concluede little.:cool:

If you do not start to do some test do not exit, even why? 100 people tell you 100 different things. You have to start from one side and go forward...

I know also..... it is all smoke and mirrors "do not listen to your friend," she wants the barrel full and the wife drunk!!

[bravosport150]

to conclude, I have to find the time. Gi? this weekend will change? fuel filter and put? the additive, then proceed with the other tests.
The thing that you do not ? happen ? if the pump tank is always a constant pressure of 3 bar, or with the increase of the accelerator in addition to the pump HP pump-tank to increase the pressure?

[msport (exil77grande)]

let's say that the post has no reason to continue if you do not do the physical tests, otherwise they are forced to close, we are 8 pages and still not nothing if not write-write and write and then people get bored and want more action to help you.

[mariodarkblue]

Guys...update...problem common also to my good...I wrote the map (so far I was riding with only the egr closed)...mapped, leaving the ORIGINAL rail...made time to 100mm3...accelero 4..tac...failure...diagnosis ?P0091...damn pump..or injectors...I have not tried to do a diagnosis in the running...with prex objective and prex measured...but I am afraid already? for the pump and injectors to check out ...(also xk? the prail ? ori, probably with the times longer, don't heat to keep it...)...

[oakley1]

Success with alfa 159 150 hp the same error in diagnosis. Replaced the high pressure pump( the problem was also once rewritten l ori)

[mariodarkblue]

Success with alfa 159 150 hp the same error in diagnosis. Replaced the high pressure pump( the problem was also once rewritten l ori)

eh I'm afraid that is she the one to blame you know...xk? the prex rail ? own the original...probably can't stay behind the times...the sensor is aware of the discrepancy between the objective/measured...and fails...

[oakley1]

In 159 of which I have spoken, the master told me that the pump on the inside was quite ruined. See a little

[bravosport150]

but with the original map to you from the failure?

[scarface]

try to put the map in the prex rail original and raises equally the pressure limiter and see what happens....
I'm on two bravo 1.9 120 hp I solved it.

[mariodarkblue]

So..tried the map ori..the defect nonsi presents...anyway the map ke had put on had the rail pressure original...only the calculated times for 100mm3...

[bravosport150]

to me with the old map that I had, even with the original pressure and limiters raised me appeared to be the failure!

[oakley1]

I think that with qi 100mm3 the demand is greater then the pump has to work a bit more?... However, the problem c'? ? I think it is the presenter? even with the map ori, sooner or later

[scarface]

if with all ori has the defect as you have suggested others take it to a pompista and you'll see that ? what is pi? that simple, even if a p? painful,why? so, it won't solve never.

[bravosport150]

have you tried to change the map?

[mariodarkblue]

Guys..useless to write in the blank...with the map mod (I repeat, rail original, just adequate time for 100mm3) the drive from p0091, with the map ori the error does not occur...
to be certain of doubt that I axle (the pump that is waving at you) I have to do a log on the march with the map mod, and record the time at which the error occurs, the pressure is objective and measured...but they are already? sure that the measured sar? lower than the target...

[bravosport150]

however, if you look at my first post in this topic where I have inserted the images of the charts, and my blood pressure was usually superior to that goal, but in the moment of failure was lower.

[mariodarkblue]

Ok...the problem is always present...got a diagnosis today...both with map rail the original and only calculated times to 100mm3, map rail moddata with bp to 100mm3...the error c'? and always...and it is verified that the prex is measured does not reach the goal...in the week, prover? to bypass fuel filter...to measure the pressure of the low...and see..

[bravosport150]

ahh ok here, we wait for the results of the tests that you will do ;)

[danny677]

surely the naphtha is missing already? before reaching the high pressure pump, as assumed

[mariodarkblue]

surely the naphtha is missing already? before reaching the high pressure pump, as assumed

forgive me...but I don't understand how you can essserne sure...may also be some injector that refuses too...or the pump simply can not hold the required pressure...I think that it is n o t to attribute the problem to the line of low pressure.

[danny677]

with those pressures in the game and an injector reluctant to shoot you in the engine without if and without but; if the pump is not holding pressure tries to compensate for the pu? thanks to the sensors, and if he can't, at the peak of his reach, he sends you, the engine stalled with the rpm not the size of the net on the power supply..

[mariodarkblue]

[danny677]

very good!
how many km of mileage has the car ?

[mariodarkblue]

92.000 km original...it's just that I am convinced that the old owner (I am the 2?)...had the module on the rail...I found the car scatalizzata and with the clutch and flywheel replaced...

[danny677]

I would say its you, 92k miles are a few to knock unna pump rail except in rare cases, then sure, a form he had. .

however, now you can have fun with the map..

[motorsport]

bravo all friend mario is glad that you have solved...;)

[blackwolf76]

ten pages of thread for a problem identified at an early stage, not bad;);)

cma the pump rail you can? break even at 10000km, just caught a bit of diesel fuel is dirty or saturated with water. On the bravo 120 I happened several with the pump and rail route, also 40/50000 km.

[bravosport150]

mario how much you have spent roughly to rebuild the pump and for how long ? gone away?

[mariodarkblue]

[tidus1985]

bravosport as it goes still get the error?

[bravosport150]

for now, I have not had the error, I'm testing with calm ;)

[engy]

for now, I have not had the error, I'm testing with calm ;)
Hi to all forum , I am engy( autoripatpre pompista common rail) ? I am new to writing ,I have read all the papiello you ? written!!!usually to have a good performance and the consumption perffetto , the hp pump , the injectors ,should be rivisionati at least every one hundred thousand miles , then especially after you made a mapping!!! that requires more precision and constant service pressure

[mariodarkblue]

Hi engy...could you explain what you found to be compliant in a pump hp?the pompista, said he had not worn...also, I have a injector that corrects most of 2mm3...the others are all 0.3 0.4...what you review in an injector?what is the cost?also in mp

[engy]

hello mario, this is a good question that you have placed me!!!! should be revised as you review the engine , it should be smondata and you are in control of the microscope, or that the organ-i, who have or has small wear and tear or v? changed or v? revisinato , then the injector is almost out of quota , then also the injectors to be reconditioned ( all ) and everything should be tried to the bench where you simulate all of the evidence of the seal body and the high pressure , I hope I have been exhaustive

[bravosport150]

engy but show you that in the entrance of the high pressure pump (where is the tube plug that comes from the fuel filter), c'? a small filter?

[engy]

depends on the pump mounted , then you postami type of car and year of manufacture and engine number , the location of the engine ereperibile on the registration card or on the name plate of aluminum that is to be the engine !!! and I will tell you that the pump clean and if it leads to the filter

[bravosport150]

for now, I can tell you that ? a fiat bravo 1.9 mjet 150 hp Sport in 2008!

[danny677]

Yesterday happened the same problem on a Gpunto 1.3 mjet 75hp, it was the filter that is under the screw from 19-to 21-all clogged up. Thoroughly cleaned, problem solved..
and to think that already? the pompista had spoken of a revision of the pump.

[bravosport150]

danny, but which screw are you referring to? How did you extract the filter?

in the fourth picture you can see the plug (the green part) of the pipe that goes from the fuel filter to the pump Hp, which I have detached.

and is also at the top is driven by the camshaft

[bravosport150]

I surrounded with red pipe that comes from the fuel filter to see that ? the one with a connection to the plug on the pump:

I saw the photos then? I can not read the number of the pump,see if you can legerllo, begins with 0445110--- see the last three numbers

[danny677]

in the last photo, at the end?, at 90 degrees c'? a nut that seems to be blind, could be the equivalent that contains the filter

[nasone147]

it's too bad the topic has been abandoned,it would have been useful to me. :(

[tidus1985]

what's your problem??

[nasone147]

Hello Tidus :-) x good luck ? a lot, if your not s is pi? live, but several times this error ? come out to me!!-.-

[tidus1985]

then, many users have fixed the fault with the new map, if it is original then I would say that has to be carefully controlled pressure regulator and rail sensopre

[Electric]

I am x pi? to clean the pump of the instrument panel and already successful in my case. I put the gun in the air in the tube that is located in the engine toward the instrument panel to the return, of course, after a big blown or reassembled everything and the car was flying and lasted for a week, then point and**** but I realized that the instrument panel was full of schivezze clean and everything ok.

[nasone147]

then, many users have fixed the fault with the new map, if it is original then I would say that has to be carefully controlled pressure regulator and rail sensopre
I also have solved "by changing the map," cio? by lowering the diesel! Then m ? happened d make a deal, pump+injectors 100 €, and the regulator gliel I changed it! Soon return? to the previous map to do the test of the 9!;-)

[enzopezzano]

as already said by blackwolf, the problem is in the pump, A/P, with high pressures and loads, high standards required instantly is not able to manage them and goes into protection. The fact that he who made you the map, you have raised the limiter, it makes me think about its preparation, as if the map has made it, he would have had to know how was the car with those values. I am sorry not to be able to view the file for my still a few messages. if you put the map ori without a dpf you will not be pi? problems most likely. if I can afford to give you a technical opinion from a layman and especially authorized Fiat, do you calibrate your injectors, have the fixes from the panic-fear.

Nasone 147, the answer you've given alone, lower diesel and no damage....... put your map mod,after you have replaced the pump and all the rest and go quiet.

[kingsnake]

I also have the same problem on a Good 120 hp and a bmw 320d 177cv, p0091 on the good and on the Bmw I can't remember the code but I d? plausibilit? rail pressure

[bravosport150]

[147q2]

it could be a problem of the map

[Tinturia]

7537

Hello all,
I have the same problem on a 147.
Monday? scriver? the map ori understand if ? a problem of the map or less.
In the meantime, I ask for your help to understand what could possibly be the problem in the map.
Thanks

[IlCurioso]

In my opinion do a mapping without make sure that ka mechanical part is ok, I think it is quite counterproductive... You should be to accentuate only the shortcomings of the mechanics! Then I cut and revision total injector-pump-turbine and also a new clutch would not hurt!

[mimmoyzf]

Hi guys I have read all the pages to figure out the problem error P0091 and if not I get it wrong and a problem of the map right?? I have a fiat bravo sport 150 hp and with the map it gives an error P0091 but with the map ori, everything works properly,,,I have made three different maps for? you...someone can? help??' thanks

[overbooster]

No ? a mechanical problem. Your pump HP is not able to reach the pressure that you require from the map, it lowers the IQ, and if you do not fix you do the checks that have been written previously.

[mimmoyzf]

And the problem is that the map me the year made I do not know to change it to the maximum I can put it in the machine, or read it...and the person it has made me assures me that and well done, and mechanical problems....

[overbooster]

I had the same problem with a 159 as soon as the spremevi a p? gave this error and traveled with increments that are still in the standard, why? the car was gold all over, after the controls at the low pressure I brought the pump HP from pompista it review and problem solved. you are practical mechanics?

[mimmoyzf]

Why? what would you recommend?If you say that I need to rebuild the pump only and it is not even why? I found a video on youtube of my pump and I can say that open and easy to the problem, and after as the texts of the pressure???

[Marcuc]

however, I can say that not all of the pompisti feel the pressure of the pump itself

[mimmoyzf]

I do not know but I believe that if you ? a piece that must withstand pressures I have to make sure that the piece to hold them up and if not what is the meaning of refurbished...?ok but then what do I do???

[Marcuc]

flaw review and be sure to try the pressure

[mimmoyzf]

hi, according to you, could be the sensor on the high pressure pump that is not working well, why? the pompista tells me that is strange that it is the pump why? the installed pump stand high performance....

[freddyecu]

From the parameters that you have put a injector is defective 4 out of herring.. correct Values from-2. To +2
