Change the fuel filter with a new one

Why does my 2000 S80 T6 sputter between 45 and 65mph?


misfire? check for bad coil (your engine has 6 coils) not hard to replace.

Duramax will not start plugged in ran then died wont start again. any ideas?


I take it that your engine is a diesel (glo-plugs) in which case the pumping of the accelerator is just good exercise for your leg but does nothing for the engine as it does not have an accelerator pump. faulty glo plugs will only make for hard starting on cold mornings so that will be out also. So the next ting that will give some idea as to the problem will be to have the fault codes read and that will show up the area and sensors that are causing your faults.

Code p0234


P0234 Description
The boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and engine speed. The engine control module (ECM) uses this information to assist in diagnosis of the barometric pressure (BARO) sensor and to provide engine overboost protection. The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The engine control module (ECM) supplies 5 volts to the boost pressure sensor on the 5-volt reference 2 circuit, and provides a ground on a low reference circuit. The boost pressure sensor provides a signal to the ECM on a signal circuit relative to the pressure changes. The ECM monitors the boost pressure sensor signal for voltage outside of the normal range. The ECM calculates a predicted value for the boost pressure sensor. The ECM then compares the predicted value to the actual signal.

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?
Did you do a hard reset after clearing the code? hope this helps!

I have fault codes po105,p1105,p0100,p0234,what is the most likely cause?


The missing codes may be Saab-specific but two were found:
- P0105= MAP/BARO Circuit Malfunction - P1105 not listed - P0100 " " - P0234= Engine Overboost Condition
If in the US or Canada, check with a chain auto parts store, they may have all of the codes.
Hope that helps-
