engine failure error P0238 sensor suction pressure plausibility

Hello guys, I'm getting crazy with being machine,
? was already a bit pacioccata before that it came from me. (the owner was convinced it was original, however, was already? pacioccata)
in attachment I put the file ori and mod files.

the machine in 4 or some times a maximum of 5 at full throttle on the 3600\4000 rpm comes in failure.
with error P0238 pressure sensor plausibilit?.

with the original file, the damage does not turn on.

in the mod file the prex turbo and golds, the machine runs well, but if spi pushes at the bottom, it has the failure,

as far as I know, on this machine ? mounted exhaust ****** from the downpipe and air filter this ? what I know)

looking at the two files, according to you, is beyond me something that I can't I understand?

or ? really the pressure sensor to replace?
I say this because? when I diagnosed the car with the diagnostics, before intervention, in the control unit had already? this that error.
xo now with the original map doesn't it ? re-presented.

give me a hand?
Thanks a lot

the machine ? a 147 1.9 16v 150cv(checked the manual) €3 edc16c8 hw986 sw047

hello surely the problem ? of the sensor ,but you, in the meantime, have you checked that the turbo is going good or if it tends to crash the geometry

the thing that makes me think, ? why? xo with the file ori not from nothing?

sorry for this ? the last mod I tried.

guys no one knows give me a help?

something definitely wrong in the map c'?, and are torque limiters for gear.
the maximum value ? 1000 and you have given values outside the extreme of the driver.
the turbo pressure ? totally original so I cannot give you an error for that.
however, trying to set the limiter pressure turbo f(APS) and limiter pressure turbo 2600 and see if you get the error anyway
and forgive the original map with the deal? gas reintroduced that so much of the egr ? closed with the maps of the hysteresis so you don't need to set the maximum value in those maps

the lim couple, I made so, on various cars, my included, in order to "delete" anyway, if you say you can? be the one I try...
in fact, the prex I have the mod but it fails anyway,
ok I try to raise the limiters turbo and APS, even if I don't understand why? having to do, since the prex in the map and golds, ok pu? increase a p? with the diesel, but not to go to failure.
as for the egr, I tried to close it by the map thinking it could be that...
prover? with the lim prex turbo arise, and we see that... thanks

reduced torque limiters, forgiven ori the limit x gear, map turbo stock, clean the pressure sensor was furniture;
the result is always the same, failure pressure soars, even up to 2.0 bar,
I don't really know pi? do.
no one knows, or could capirene why

let me this test with the engine off and ignition on atmospheric pressure and intake manifold tell me how ? ?

I've already done the test..
Press. Atm 998
Press. Asp 1012

too much fuel, and thus the prex turbo increases,especially if and skat
I stoop to the rail and t inj, then by the 200pt the rev limiter turbo including the last bit then 0F89E8 to 0F8BE8 as I said earlier, good magi
and abbassarei the last 4 curves of the maps an overboost ,in order to lower the peak of the prex turbo
said this before checking the sensor prex absolute,pierburg ,and any loss from the charge-air cooler or tubes.

I don't understand then why in the maps pedal ? went to tap the bp after the 5200 rpm....
then in the maps turbo I have seen increases in%, ranging from almost 15% to a minimum of 6.5%, but in the limiters are more low percentage...arrivals to 6.3 per cent, the same is true for maps of the rail and its limiters....
I've also seen advances right to the laps where laments the problem of the 21% more....that you've gone from 19 degrees to 23...for many on a diesel given that they usually increase to a maximum of 3 degrees...***** o the main problem as he also says pinotec ? you gave a lot of diesel between-times,rail, and advances and, therefore, the turbo salt because it is unable to remove all of the volume of the gas.....now you have two possibilities? or systems the map, or seek to intervene on the duty cycle vgt by special map....but ? very difficult to do....
ah..then I wanted to say that the mod is made to the percentage of gas released in the "style edc15" it has no utility?....
the egr ? already closed by the "4 panettoni" control for which the mod is not needed...

I would like to add that the torque limiters,also that of the reverse!!,the facts in that way are very questionable....
the cio? they are basically all made "a team"....

I'm coming crazy I also with the same issue, the same machine,euro 3 150hp edc16c8, the turbo rises above 2 bar, even if the pressure turbo I go with the original.

address e646c "limiter, turbo, differential," it should be raised ? set to 1.6

according to me the prex rail ? too high I don't see the reason of all is prex the lim couple does not ? appropriate to the pedal then I do not understand the 2469 the lim torque x gear are too many high map the quantity of gas and "similar" in that way according to me is not necessary, and may give you well in trouble...just controls the amount of gas introduced, and similar maps do not need to do it in this way, and then ? true as it says franco75 you can mod the bit limiter turbo and down a little times

Unmount the turbine and clean up the geometry. sure son jump to the swirl and passing through the valves are finished in the turbine by blocking the proper functioning of the geometry. You can check the race that the dipstick by detaching and attaching the tube to the wastgate a car in motion.

3, car 4, with this mail I have given this problem, on one of the 3 I tried to change the map, but nothing to do, even with the turbo pressure of the original makes the over-all the evidence that you have mentioned so far, I have tried, but without any result

this model of car does not fit the swirl, I checked yesterday evening, in practice, the first models of the jtdm 150 hp with the edc16c8 are of the 140 horses "hidden"

With rail pressure and original torque limiter gear original to me the problem ? occurred equally

Also made this test, the result ? always the same

it has been set? pressure peaks do you have?

From diagnosis to 3000 square mar fixed as it speeds up, 3 up, in practice, the Map gets to the bottom of the scale.

Change the sensor from the numbers and put the right one

Gi? fact, the Map I have already? replaced, but without result

Not ? the Map that is mad, ? the pressure goes really, in fact, during one of these tests ? also exploded a sleeve

just for that reason ? the turbine to be having problems. Try to plug the tube that goes to the wastgate and see if they resurface the defect. At that point we exclude the problem of electronic...

then the second you get to 3 Bars?

3000 mbar means that the turbo comes in at least 2 bar pressure, 3 bars absolute pressure...

3 machines with the same problem I exclude a priori and then if it was a problem of the geometry of the turbo or of the control valve, the problem should occur with the file ori

Guys sorry if I open the post, I have a alfa gt 150cv edc16c8 with the same problem, I tried to change the map but it fails the same... the variable geometry cold-works well I also did the manual activation and it makes the whole race... the problem manifests itself with the gears lughe type, the fourth... what could it be?

I personally have fixed by disassembling the turbo, the snail on the discharge side and cleaning the geometry of the turbo

Check the wiring up allacentralina

meanwhile, he began to check the sensor, is mapped?

The drive is mapped, but have started to us after several months, which always has the same map...then find the map. Leo_sg the map sensor you say? Because I already tried to change, and should always be faulty.

Clean up the geometry variable is the one that does not flow well.

the same problem ank'io
