Alfa 156 problem turbo pressure

[Matty23p]

Hello guys, I have a problem on a 156 1.9 16v edc16c8...gives me this error P1235 - pressure signal turbo. The car is original except the egr... I tried to clean the map sensor and clear the error, for a couple of weeks went well, then reappeared... the car is only damaged and not in recovery, I did a log and follows the pressure of the turbo as the map.... What can be causing this failure? Thanks

[munro]

the map sensor is gone...

[Matty23p]

Thanks Munro, I try to change it to see if there is more...

[Alfiuccio]

I agree with munro....go quiet

[Matty23p]

Thanks guys, I tried to change it and now I do not follow more than the turbo pressure...between the object and the measured there, and 0.2 less... to the point I can be the solenoid valve?

But the car is off, the measured value corresponds to the atmospheric pressure? Check this first

[Matty23p]

No they do not match, the atmospheric pressure, I 995, and the measured value 960.

[munro]

look at the code of the map can be different..
not that you have fitted a 3 bar instead of the 2.5?

Hello, on these machines a year these problem on turbine crashes to the variable geometry, you should check manually if the geometry v and ****** and if it's the whole race...

quoto todos...has the variable geometry dirty or blocked...hole clean
