Chrysler Concorde, Code p1391

Code p1391 keeps showing up on the on board diagnostic system on my 1999 Chrysler Concorde and I would like to know how to fix it

Steve Says,

Thanks for asking me your code question. Code P1391 is for intermittent loss of CMP (camshaft) or CKP (crankshaft) sensors.

You can either replace then both or test each one to find out which one it is or if it is a problem with the wiring.

If you would like to get the tests or more advice or help from dealer level technicians then just type your question into the blue box below:
