View The Full Version : Pressure P0235 turbocharger
Hello to all:)
guys I ask of you who have more experience than me..
I have an alfa 147 1.9 jtd 115hp mapped.. two months ago I had to
remove the modified map and put the original one to do the review
here in Germany where I live.. made the review I loaded into the ecu via the serial
the map mod that I had and here starts the problem:(
if I start to pull the gears before or after the light comes on engine red, and if I keep my
immediately the foot from the accelerator, the car goes into recovery and does not accelerate more...
precise also that from 2500 to 3000 rpm, the car has more power and be sluggish..
it can be been writing the wrong file? I find the egr valve, piping and
variable geometry of the turbine since the valve ? was closed with a plate
mettallica and the surveyors ? been clean 2 weeks ago.. you could also take a look
the file that I have attached? It is the map that I have in my car for many years now. The precise
I have done I saw that I still don't know how to change the maps..
appearance your advice
thanks in advance:)
guys sorry I forgot to tell you that in diagnosis me error like the P0235 turbocharger turbine and the egr valve is always active.. I have also noticed that the machine does not go beyond 190 km / h.. I remember that just mapped, I even could take the 215 km per hour without problem.*****o the light engine turns on only if I accelerate
shot at it, and not gently..
Seems to be a problem with the geometry of the turbo that blocks... you need to verify that flick free, or it could also be the sensor on the pressure, but before checking geometry...
if you want an opinion on the mod you have to post the original as well, in any case, if the first was good, I don't see how it can be ruined just rewriting it, you wrote that ? been clean 2 weeks ago geometry, such as that of the turbo? if you ? the state made a mistake, surely they', please check from someone who has done the job.

Hello Marcuc , I also Think it's the pressure sensor. Where do you live in Germany .if you are in my vicinity, I could give a hand .
Hello check the tube that adjusts the valve of the variable geometry turbine;
Hello check the tube that adjusts the valve of the variable geometry turbine;
If it was a prob. the vacuum pipe would complain that is not performance, but I seem to have figured out that if he pulls the first gear goes in recovery usually classic defect geometry lasts... or pressure sensor that reads the wrong or dirty if you still have the egr active...
thanks guys for responding to my help.*****s, I've double-checked the variable geometry of the turbine and ? free..I rismontato also the pressure sensor, and I did not find it dirty.. anyway Friday arrives the sensor in the warehouse, and I try to change it with a new one.. but the thing that's still strange ? that is the problem ? started immediately after the writing of the map mod.. will update after trying the machine with the pressure sensor new
this should be the original map of the machine..I would appreciate your comments..hoping that I have made a decent mapping :confused:

hello 159..unfortunately we are very far apart :(
I am 30 km from the border of austria
hello guys.*****and said, I have mounted the sensor the new pressure..the machine, however, does not go as it should..
the problem of the vacuum of power by 2500-3000 rpm, unfortunately, persists..I checked all the tubes of variable geometry..all healthy even why? I have changed all of a couple of months ago, in view of the rupture of the tubes..you say that the map has nothing to do with the problem? as ever, the machine should not be more as it went before the writing of the original file?

Egr have closed only by the map... why? it may also be the the problem to try you should if you have not already done also close it with a plate.

Hi silven. The plate c'? gi?. About the map I could not tell you since I do not know how to map a drive

I noticed only now your answer...in addition to the tubes of the command geometry, you have to check 1 that there is a loss of depression from the plant could also be the tank of the vacuum or any other vacuum pump connected that has a leak or broken, and therefore makes you have less "empty" (and therefore pressure to the turbo...) to the command of the geometry, you should be looking to make a quick test if you don't have the tools to check the vacuum by putting it in the bike (making you someone to help,) looking at the auction of the geometry if it is within two seconds from the start to the end of the stroke in depression, if within this time, it goes to the bottom or remains at the destination c'? a leak on the vacuum system. 2 verify as I have already? said that the geometry of the turbo (the mechanical part) is free why? if ? hard or partially blocked the depression did not c'? the fa run it...check carefully or make sure that these things which I have said to you, and you will see that resolve.

hi silven. excuse the late response. then I did all the tests you listed. I found no loss in the system of depression, unfortunately, but I have noticed that when a friend of mine has switched on the framework, the rod of variable geometry ? dropped immediately at the end of the stroke ... and when he set in motion the rod of the geometry ? always remained to the end of the stroke
The strange thing is that when you turned it on the picture you have seen him moving the rod... to make you better understand when you turn on the engine the rod should be from the part of the lung (practically where it enters the vacuum pipe of the valve.. ) if, instead, when you turn on the picture you see that you "download" means ? the solenoid valve command that has a problem.

in fact ? this is the strange thing..the variable geometry open fully as soon as I turn the picture..and when I put in motion the car, however, always remains open..that's why? wondering if you could depend on to write the wrong of the map..I repeat, this problem ? all started after rewriting the mod file
