2001 pt cruizer has a code p1391 can you tell me what that code means. I have replaced spark plugs and wires, coil pack, and a new battery. I have replaced everything but the alternator. I'm getting a code of the ignition system or misfire. What could this mean. The engine light came on.
This is a faulty code of either cam or crank angle sensor, have you look here as yet? As they share the same code, I would do the crank angle first as these are more common to fail, but it is really a 50/50 bet.
