P0016 For no good reason

[Holmessato]

Just changed Cam cover today to resolve an oil leak, and P0016 came up after a mile or so. Cleared it and it came back immidiately. Cam sensor was correctly seated in the new cover and connections are good. All checked out fine.
No performance issues, runs fine (oil leaks around cover seem cured too), just the one code.
Timing chain was done a year or so back, and there has not been any P0016 since Ive owned it. Timing chain and tensioner looked spot on today when I had the cover off.
Can only imagine the sensor is ultra sensitive to gap to the cam and the new cover may just be moving it fractionally further away (or new oil seal thats not so crushed causes it to stan higher?).
I was unbelieveable carefull while doing the work, so cant beleive Ill have harmed anything else.
New sensor on order but from reading previous posts Im not holding my breath.

Has anyone ever solved this issue? Ive seen at least 2 other posts with exactly the same scenario...and seems the issue was not fixed before despair and giving up.
I dont mean when its caused by stretched timing chain or incorrect timing, because thats deffinitly not the issue here.

Carefull with the wiring to the cam and cranck sensor as they are finicky AF. Both sensors work together so generally when you change/clean 1 you should do the other as well...

That’s unfortunate mate, I had a similar issue, changed the hpfp and after a couple of days it threw the p0016 up, camshaft crankshaft correlation, each and every time I’ve had a p0116 code I’ve replaced the timing chain kit.
the timing only has to be slightly out for it to throw the code up, you could change the camshaft position sensor first and see but I believe when that goes it throws a different fault code up. Good luck

Did you buy a genuine rocker cover? I’ve heard that some aftermarket covers can have faults with the PCV there’s a YouTube video on it, long shot but I we’re talking to a Peugeot specialist about the rocker cover leaking and he said he’s known the 0016 code to crop up if the cover is not airtight
