PT Criuser has been running hot and now makes a loud chirping sound when cranked up . What causes this ?


my guess is your water pump is not working properly and the loud chirping sound is from the serpentine belt which also runs the water pump, alternator, ac and steering pump. first thing to check is coolant the cooling fan , thermostat , water pump in this order. chirping sound definitely come from the belt but the cause could come from any of the driven part but im zeroing in on the water pump because the car is running hot. old belt could also cause the chirping.

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.

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-
