Can't Eliminate P0369 Code

[stphnsns]

Hi all, I have a 2004 Cayenne V6, with 118K miles, that is repeatedly throwing the P0369 code for camshaft position sensor issue. We've replaced BOTH sensors, but are still getting the code, usually within 10 running minutes of erasing it. With both sensors being new, it's perplexing. The truck runs and drives great, with no noticeable noises or issues. I've seen a few cases in my research, where a faulty timing chain tensioner could cause this (or a stretched chain), but in all those cases the code was accompanied by a knock &/or poor performance. I could leave it, but I feel there has to be a reason the code is being thrown. I don't believe the new cam position sensors need calibrated? Any help, advice or suggestions from the knowledgeable community would be appreciated! Thank you in advance.

Did you check camshaft rotor for damage.

Thanks Loren, I have not. Is this an easy check/replacement? Thank you!!

Also:

• A dead/weak battery
• A faulty starter motor
• A starting system circuit
• Camshaft position sensor circuit poor electrical connection
• A faulty camshaft position sensor
• A camshaft position sensor harness that is shorted or open
• A camshaft position sensor circuit that has a poor electrical connection

Thanks for the post. I think we've kind of eliminated those other possibilities. I would assume a bad battery would throw erratic codes, and not the same one every time. Plus the car starts, runs, and drives great - even after sitting for a few days. I did go through the process of accessing the battery to be sure (even disconnected it to reset it), and it seems fine. All the connections, etc are good. Thank you for the suggestions though!

Did you ever get resolution to this? I have the same suv and motor that started exhibiting these symptoms. I've changed both cmp sensors to no avail. I've checked wires and even wiggled the ECM wires for a bad connection. I could start testing wires for fault but I don't believe it has anything to do with the sensors. Any help please??

Hi, not completely, as I haven't had much time for diagnosis lately. This is a winter truck for me, so will probably figure it out come spring when the cars come back out and the truck goes to bed (it drives fine, with no issue, so I haven't been sweating it too much, other than the annoying CE light). But anyway, based on all my findings, so far, I kind of have it narrowed down to the camshaft rotor (or phase wheel, as it's sometimes referred to), as Loren suggested above. It seems this wheel is easily bent when working in this area, and can cause the same error code (P0369). I'm hoping that's the case, as I'll otherwise be stumped. Please let me know if you solve it on your end, as I'll probably be looking to figure mine out in another month or so, if not before!

Thanks for the reply. Im stumped. Mine has trouble starting. Got a new code of p0016 with it. I'll prob have to bite the bullet and take it to the stealer ship to have the cam and crank checked to see if the timing has stretched or jumped. Thanks.

Yuk, sorry to hear it, as that sounds painful. I hope there's a simple and cost effective solution for you. Keep us posted please!

Took it to the stealership. Actually was a good experience but bad news. Said the timing chains need to be replaced. Talking 9k to do the job.

Ouch! Mercy. Though I would hope a good indy could do it for roughly 50-60% of that figure? Regardless, I wish you all the best in getting it back on the road.
