2012 Buick Park Avenue Repair Question
Mileage: No information provided.
92 P/A Ultra/Super-3800-150km - stalls and won't start
Asked by wipers park avenue 1992Answer
Those had issues with the coils, ignition modules, crank angle sensors, and cam sensors. Code 17 is RPM signal problem, could be the cam or crank sensor. The code 56 is a Quad driver fault, most likely needs a new ECM to fix that one
crank sensor/cam sensor or ECM - which one would you change first?
Where is the cam sensor and where is the crank sensor?
Please and thanks for the help!
According to the trouble codes,I would install a crank sensor and a PCM
Thanks! Installed a new crank sensor and repaired the wiring harness as it had taken some heat. Car starts, runs fine and no more stalls or no start. Code 17 is gone.
Intermittent 56 still shows up. Does removing the negative gnd cable reset intermittent faults or do I have to wait for x number of restarts? Do I need a new PCM or could I be waiting for more headache?
If it is intermittent, it will just keep coming back.The quad driver code is withing ht ePCM and will most likely come back until the PCM is replaced, it is just like a driver for your pc.
