Another p000b issue is if a vehicle overheats from a coolant leak or lack of coolant, it can essentially destroy the camshaft position sensor which then needs to be replaced.
Just got this error code with my new 3.6 I installed over the summer. I got this with our old one, had a head gasket failure so replaced the entire engine, now getting with the new. I did mix Castrol and Mobil1 but they were both 0w20. Could there be additives in each not reacting well? 30 PSI oil pressure consistently and I'm pretty sure the oil level is good, will check again. Which sensor could go bad that would also cause this? I know of 4 on each bank, two on the side and two on the top. Maybe one of those???
hey dude great video, ive been working on a 2016 town and country 3.6. it had a p0344 code for a bad cam reading. i replaced the camshaft, ocv and the phaser. after fixing that i had the p000b come on it drives fine but that code comes back. the oil was changed recently and the p000b was not there originally until i changed all the parts. i looked to make sure it wasnt out of time and it wasnt. i cant get the vehicle to do the cam/crank relearn and the degree for the phaser is maxed out. i dont think the oil was wrong from who did it but maybe. just wondering if you had any idea of where i could look next??
Thanks for watching! If you have access to a good scan tool there is a function called “cam phaser cleaning” and that’s the very first thing I would try, do it a few times, clear out the code and see if that takes care of it, if that does t take care of it I would 100% try changing the oil again and make sure that you use an OEM Mopar filter and the right fluid your vehicle calls for, because it will definitely cause that issue as well.
@@thehowardsgarage2480 thanks. I'll definitely try that. I put the old phaser and ocv on and have the same outcome. Idk if the phasers are bad or the new one came bad from wherever. It was Mopar but not sure if its just defective or how it was handled. It did have the p0344 before the oil change. But not the p000b. I've done the cleaning but ill try it a few more times before the oil change. But the oil is pretty much the last thing I've wanted to do. Thanks for the help. I'll give you an update when I find anything. Much thanks!
@@kipamore ok so the original camshaft magnetic timing wheel was bad. Found that with the lab scope so we replaced the camshaft. Then the computer was showing data that the cam was like 90deg off time. But it ran fine so if it was that far out it would have hit some valves and pistons. It would not do a cam crank relearn at all. No computer reflash would work and all the position sensors were fine. No mechanical or oil issue. For some reason the computer just wouldnt reset or learn. So eventually we had to wire the the bad cam position sensor side wires with the good side. Making it see one position sensor as both sides since they are pretty identical when on a lab scope Do a cam crank relearn and then it went through with the relearn. Rewired the cam position sensors and redid the relearn and it fixed it self. The computer was messed up but there was no refresh so we tricked it to work and now it's fine
@@jimmymartinez7800 Man, that's helpful. I actually had thought to do that, but I assumed it would make it worse since the other bank's cam sensor wouldn't match up. But it kinda mades sense, as then you put one cam at it's "marked" position, the other is in position as well. This damn van is a big albatross around my neck. 2 years ago it went to the dealer, they threw parts at it like crazy, finally throwing an entire engine at it, replaced the ECM, ran new wires from the cam sensor to the ECU, new pins at the ECU, opened a case with FCA, blah blah blah. Eventually they just turned the customer away unfixed. Now it falls to me to figure something out. Let me ask you this: it seems like P000b is one of those codes that's cumulative - takes a while to set. When it does, it puts the van in limp. What I'm wondering is in your case, did clearing the codes take it out of limp? Or otherwise make it so it would take a while for the code to reappear, or was it instant. That's my utter failure mode - selling the customer a Foxwell scanner that can reset the code. Won't be a proud day if that happens.
I have a 2011 hemi grand cherokee. Had this code come on when I was a quart low, then added Lucas and it came on, flushed it out, came on, and then did the cam shaft sensor and still came on. Not sure what to do now besides bring it in.
I have the same jeep v8 and the same problem recently replace the sensor and the check engine was off for 2 days now I turn on again with the p000b code

@@jimmymartinez7800 I'm chasing this problem myself. What was your fix?

This engine just sucks in general 😂
