Wife’s 2001 Jeep GC Overland is driving me nuts. 130k on it. Valvoline synthetic since we owned it last 50k miles or so.
About Thanksgiving threw the p0344 cam code. Put a new standard motor sensor in it. I wasn’t able to relearn it with my solus so Cleared code and went away for 3-4 days then came back. Drove fine, no missing or limp mode. Every great once in a while traction control light would come on. Anyway took it to dealer. They tested it, said not a Mopar sensor and that’s the issue. They put a Mopar one in it. 3 days later light back on. Took it back and they put a new cam phaser sensor in it they said, same thing. They’re stumped.
I pulled front off the motor a little before Christmas. The guide on the timing chain was broke and broke a bolt off in the block. The cam reluctor appeared fine. I put a new cloyes chain on it, guides, sprockets, new oil pump and the cam reluctor.
Started perfect, runs fine. But 3-4 days later light back on. I put a different Mopar sensor in it thinking maybe a broken piece of the guide maybe hit the previous sensor. No change.
I’ve got 5V on one of the three wires to the sensor, a good ground and I’ve traced wiring back to pcm. Shook wiring etc and voltage and ground don’t fluctuate. I’m to the point I think it has to be a pcm? I can’t see it being a cam issue. I’ve tried to learn the cam/crank multiple times and still won’t do it. Tried a different scanner from my snap on guy and still nothing. I asked dealer if they attempted either time it was there and keep getting vague answers so I’m guessing no.
Any one with other thoughts? Thank you.

Yeah levels good. It threw the code initially about 1500mi after an oil change but was still right to the top.
After I did all the timing work I changed it again as I had the pan off to get all the pieces. I changed to Mobil 1 now for the heck of it. We’re still driving. I’ll clear the code once a week or whatever. Hoping whatever it is just pukes totally and makes itself known.
Thanks for the video link. He had a misfire code though, I haven’t had one of them yet. Just the cam code. The LS motors do that crap all the time.

Check out the other sensors on that common 5 volt feed if memory serves me correct the oil pressure sensor shares the feed. If one of the other sensors pulls the 5 volt low it may trigger the fault. Fixed this fault on an early 5.7 by replacing the oil pressure sensor which was shorted. Doug Doug is right as on many cars the AC pressure transducer also shares the 5 volt feed. I had an Intrepid once that would not start because that AC press transducer was shorting the 5 volt feed to ground. Ron

If I remember correctly, some scan tools can’t differentiate the cam and crank sensors. Might look at the one down on crank, I usually have a spare one laying around of both sensors just to pop in and try. They are real simple to change on pickups, GC could be harder to get to. Jim.

You are right as I remember in Chrysler training the teacher said sometimes even the PCM cant tell for sure and could set a cam sensor code when the crank sensor may be the problem and vice versa. At the Dealer we would recommend to replace both to be sure it was fixed. Ron
