Do you know the fault code? There are multiple sensors that go to the ecm. Thanks.

Customer: replied 6 years ago.
the code is PO320...............think it was ignition sensor
Expert:  Dan replied 6 years ago.

This code is usually caused by a failed crankshaft position sensor....possibly wiring or camshaft position sensor, I'd start by replacing crank sensor. Here is a picture of sensor on transmission housing, let me know if you have questions. Thanks.
