Question about 1999 Jeep Cherokee
I have a PO 1391 "Check Engine Light Code" I have recently replaced the Distributor Switch Plate . I believe this is the same as the "Camshaft Position Sensor?" I'm I correct in assuming that is correct. I couldn't erase the PO 1391 code even with the use of a scanner. How do you erase this code? Thanks. Phil

The Camshaft Position Sensor (CMP) on the 4.7L V - 8 engine is bolted to the front side of the right cylinder head. Disconnect the sensors connector. Take out the bolt that holds the sensor in place. Lightly pry out the sensor being careful not to break it. Clean out the hole and install the new sensor( put a little oil on the new sensors o-ring to help installation).

You need to put the harmonic balance for the 96 jeep on this motor,then put the crankshaft sensor on for the 96 jeep on the vehicle,this should fix you up.The crankshaft sensor and the harmonic balance have to go together.If I can be further help,let me know.>>firstname.lastname@example.org

Testimonial: "Roniecon was extremely helpful trying to solve this problem, he hung in there to the very end. He spent a lot of time researching the problem. THANKS"
The P1391 code indicates that the crank or cam sensor(s) have sent an intermitant code to the ecm. The most common cause for this is loose wiring or debris on the contacts of one of the sensors.
