P023D-22 (2C) Manifold absolute pressure - turbocharger/supercharger boost sensor A correlation - General signal failure - signal amplitude>maximum
good morning aulro!
the problem: car goes into limp mode
when it happens: upon the first 5min of driving on a cold start.
doesnt happen every time, the colder the ambient temp, the more likey it will go into limp mode. happens most times or even multiple times at 5 degrees, happens less often at 30 degrees and only once.
problem only seems to happen while on moderate throttle loads, so im assuming moderate boost.
i dont run the engine on full throttle/boost when cold
problem doesnt seem to happen at light throttle/boost loads.
problem is getting worse, ie, its happening more often.
if i let the engine idle for 5min before driving, problem happens less.
fault code is being read from the iid gap tool.
what i've done so far: smoke tested the intake manifold, no leaks, have tested a few times.
what i want: explanation of the fault code.
explanation of whats happening.
ideas on how to fix.
1million dollars please.
