1996 Cherokee 4.0L throwing code P1391?
Hi there,
Trying to figure out this issue with my wifes Cherokee. It's a 1996 4.0L 4wd Auto with ~150k.
Throwing code P1391 - Intermittent loss of CMP or CKP. I have already swapped out the cam and crank sensors, but still getting the code.
I am going to look over all the wiring tonight, but is there anything else that could be throwing this code that I should look out for?
Thanks.

P1391 FIX
Had the same problem with my truck for about 6 months now and just now figured out how to fix it. I had replaced both sensors, checked the circuit, and replaced most of the ignition system, and nothing. had a jeep mechanic give me this advice and it worked. I replaced the distributor, the whole thing, shaft and all, and the CEL is gone! apparently these are prone to wear and its just enough to cause the code. the distributor should run you about 50 bucks, but you will probably have to pay a 75 dollar core charge. i replaced mine in the parking lot of autozone so i wouldn't have to pay the core. Yes, its that easy. you will need a phillips head screwdriver and a 1/2" wrench. pay attention the distributor position on the way out and be sure to put the new one in the same way. they should also have the code reader to reset the code. Let me know if this fixes your problem.
