Would a faulty DIM on a volvo affect turbo function...p0234?


Overboost could be caused by anything from a faulty TCV, split hose or dirty MAP sensor. A replacement DIM won't change the running of the engine.

Turbo overboost po234. how to correct?


p0234 is engine over boost condition. According to Volvo P0234 is a turbo control valve. Maybe a wiring issue?

Overboost condition


Hello, your car is probaly a variale vane turbo fitted and all you need to do is seperate the VNT part of the turbo, give it a good clean with brake/carb cleaner get rid of the sticky oily residue which makes the vanes stick on turbo causing a overboost fault, a delearship might tell you that your car has been remapped at some time setting the boost RPM at like 14 or 1500 and it should be like 2200 I do not know the specifics on your vehicle but a good auto manual will tell you at which RPM your boost should build. I would have a diagnostic done and see if this is your problem, if so do the above and go back and see if it fixed your overboost problem. If not, you will need your ECU remapped. I hope this fixes your problem!

This is what my code scanner says:
P0234 Engine Overboost Condition
If you have a non-turbo model, then it's probably something else. It may be a bad turbo overboost switch. My S80 is non-turbo but I had an overboost switch go out on my Mercedes and it shut down the turbo but I had the same error message. Good luck!
