Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I'll try to help with your question.
Your Pacifica does not user a Mass Air Flow sensor, so it would not be an issue.
Could you describe the concern that you are having in more detail please?
Thanks for the detailed response. They may have referred to a MAP sensor (manifold absolute pressure).It sounds like the engine stalled and the lights coming on that you described are usually lit up when that happens. The power steering would stop working because the engine stopped running and turning the pump. A MAP sensor fault could cause the engine to stall, but it would normally set a fault code and turn on your check engine light.Does your check engine light stay on when the car is running? If it does there will be a stored trouble code that will help with the diagnosis.
Yes, the engine runs the power steering pump by the serpentine belt. The only way for the power steering to stop working abruptly would be for the engine to stall. The oil light comes on at 4 psi or lower. If the oil pressure was that low with the engine running, it would likely seize up. I think the rest of the lights coming on is similar to a bulb check that it does when it has key on but not engine running. I would have the oil pressure sending unit inspected for oil seeping into the wiring connector. I have seen this on a lot of chryslers and it interrupts the sensor signals to the computer causing the engine to stall.
There are many issues with TIPMs but I don't like to jump to that conclusion without a lot of diagnosis. TIPM modules are between $600-$700 and half to be programmed to the car by the dealer. If it doesn't fix the problem, you can't return it because once it is programmed to the car it can't be erased and used again. The TIPM controls a lot of systems on the car so I don't know what symptoms have pointed you to the tipm. Do you have any sources for me to look over?
Correction : $827.00 list price
I would suggest that you have the used car dealer take the car to a Chrysler dealership to have it diagnosed. Assuming it has a 90 day warranty from the dealer that you bought it from. This may be a diagnosis that is beyond the capability of the used car dealer's technician.
