Explained better.. The car goes into recovery?? ? mapped??
the problem may be related to the valves swirll or the throttle regulating the flow..

hello or checked in my list of errors obd and it brings me back: Malfunction P1238 fuel pump Secondary circuit
I hope is helpful for you.....

check the regulator, low pressure diesel.....

or the electric fuel pump in-tank low pressure fuel.....
to made me mad the most? or less like a giulietta 1,6 mjet which every time he stopped for the road with the fuse of the pump tank jumped....
in conclusion, I had to replace the pump, why? absorbed more current than that required by jumping the relevant fuse.....

it could be the egr closed evil! or maybe the sensor egr" but to be sure, you can do a bit of trials..

the test to do ? this : forgive but the original map , remove the egr and check that the hole in the intake manifold is ****** !!
sometimes it fills with sludge to such a point that clog completely !! clean well for the mechanical part of the egr and replace the electronic part
sometimes it happens that oxidize internally and the plunger fails to exit well

you right!! I pinotuning. test and should solve.put yourself in the hand of a diagnosis and check if it opens and closes quietly after you have cleaned it, and then delete it from the sw.go quiet!! at least we try time and also a good thing that you do.....

the machine should not be in recovery concept, the machine and gold,the egr I removed I and sn safe ? well done ,anyway, and the old system i.e. 16/c8 then the four curves, anyway,its electronic egr ? fails, in fact, today I installed a egr on the outside that dangling and till now has not given me any indicator,the error that I have listed P1238,? what I said I
why is autocom that ******** me the same thing,and this error is always, however, do not turn on any light, i.e. the gates, and after a while reappears but the machine it is fine and does not turn on no light....ok. thanks raga....

sorry, but if the error Malfunction P1238 fuel pump Secondary circuit refers to the power circuit of the fuel because you continue to say to check and try to clean the egr???
I do not understand....and as if you went to the doctor for a sore tooth, and this way the suppositories for constipation.....
mahhhh.....

mahhhh.....
I'm sorry but have you read the fault code???? the code p1238 refers to "Quantity air "
I don't understand where you got that reference to the circuit Malfunction Secondary fuel pump:confused:

marcusmagic
20-02-2013, 17:41
but in fact!! where have you seen that was a failure of the power supply circuit of the fuel pump?? it has nothing to do..the pills were right for the toothache....:D

no raga I have not solved ,the patient ? still sick sn in the test...now I have hung up the egr and you ? turned on the engine failure ...but that error of the air-c'? always, and not if he goes you have the idea of what it could be.... capitemi well the car has always the fault P1238 and the light engine does not start, ok when I plug in the valve fails, the light comes on ok ,and then for that ? the egr for the error I have left in memory but will not turn on no light????

I'm on auto date the nn found .... on the internet think that there is a quantity of air ... pero my list that I gave a friend of mine eletrauto and tells me P1238=secondary Circuit fuel pump (control module, fuel pump) test nn cost you anything.. hello

if you make a diagnosis with the Examiner fiat, you'll see that the error p1238 ? referring to "Quantity air"

Surely you are right but the problem remains.... he kiesto a consijio I give my is him determine what to do about each and every one of us says a forum there for this...
My catalog I P1238=secondary Circuit fuel pump (control module, fuel pump) if you want to control it, or you feel a pompista kiama a offices efficiently. choice of wired alpha to his liking... but must get to solve the problem... hello

Quoto perfectly the problem relates to the quantity? the air above objective value or under value or plausibilit?.. there are multiple tables of the fault codes, E0, E1, E2, etc.. in this case it is the E4, for more details a better diagnosis as the official examiner..
this problem can? depend on some hose of the depression is slightly damaged which sucks in the air, or from the egr valve..

raga I apologize in advance with all of you ,,,,,you say why? .... I made a gaf EXAGGERATED...... I had closed 24bit for each curve instead of 25..... if it went all away ,,.
luckily I noticed that the egr could emulate bad then I looked at the map and I was wrong..... anyway, to recap .....
the machine ? come to me with dibimetro changed put the new cn error P1238 (speed? air flow) ...then I cleaned her with degreaser, dry ,rimontandolo
I've seen the emulation in the chart and it was fine,,, and always with the error, but the machine was fine,,, ,egr cmq route why? wrapped he lit the lamp dtc then I put new egr and removed electronically the egr well the error ? disappeared and drive ok.... thanks to all, I apologize again
discussion closed because the car is fine .....

so, when you get error P1238 know that 90% can be the egr.... but don't exclude other things ok... a greeting

towel, I told you that if you do not closed your well, the egr valve is in the map could give you problems;), anyway the most important thing is that you fixed it..ciaoooo

if you don't make mistakes in the beginning I gave the solution, and I told you to replace the original file !!
I worked for years in the fiat, and with the Examiner !! and this error was very common on many cars
however at the end it makes me glad that you have solved , hello

pinotuning
21-02-2013, 14:43
no, do not throw anything... the speech ? another one !! sometimes the fault codes differ by a house-mother to another , this does not mean
your list is to throw !! well I like you, I have a list and it says that the code p1238 means "malfunction pump, etc....
but next to c'? written the following DTC may be subject to variations between home mother to another !
in other fault codes not ? specified that can be subject to changes !!
then don't throw anything !! always trust the experience and a good diagnosis !!
hello
