P0340 Cam Shaft sensor??
Ok guys and gals, I have a 1999 Cherokee 4.0 auto that is throwing the code P0340 "Camshaft position sensor A circuit bank 1 or single sensor" and P1391 which I don't know what the heck that is!!!!!!!! My understanding is there is not a cam shaft sensor on the year because it has a distributor???? Not sure where to start on this one. Any help?? I forgot to mention the jeep runs fine. So far no problems what so ever.

Check the wires coming out of the distributor for bare spots and detach the connector and clean both sides out with CRC Electronic Cleaner.
P0340 and P1391 (loss of cam or crank sensor signal at the PCM) usually go together.
Clear the codes by disconnecting the batt negative cable for about five minutes, or use a code reader to clear the codes, wiggle the wiring harnesses, crank it up and see if the codes return.
You may have a bad cam sensor (Switch Plate as Chrysler calls it) in the long run.
