Is there a code for too hi of boost pressure ? If so,what psi will the computer log the code? I`m thinkin of making an adjustible boost elbow and don`t want to set off any codes. Thanx

 

P0234 Turbocharger Overboost Condition
P0236 Turbocharger Boost Pressure Sensor Performance / Rationality
P0237 Turbocharger Boost Pressure Sensor Low
P0238 Turbocharger Boost Pressure Sensor High
P0251 Injection Pump Fuel Valve Feedback

There are a number of codes set for overboost conditions. I think overboost values are kept in the ecm even after the codes clear, but this is just guess based on other posts on ECM stored values.

 

ya, i just cleared mine, i gotta take my performance stuff off and take it in for the injectors. i have a leaky one or two. But my friend went in and they dug deep and found the high boost code. All he told them is he was on the coast(vancouver island canada). They said well it should not raise it that much, but they bought it and replaced all six injectors for the 100 dollar deductable. But i think im gonna go with the honned injectors from DDP.

 

p0234 i have it all the time clear it one a week. no problem
