P0344 camshaft sensor - again...

CEL came back on again today, threw P0344 camshaft code again. Been through this before. Changed the sensor out a couple times with parts store sensor, with no success. Ended up changing the OPDA to a crown unit and put and currently have an OEM sensor. Should I try to swap the sensor out again with another OEM model? Check the OPDA again?

Not sure where to go from here, any ideas and help?

If the alignment on the OPDA is off it will throw a code.

How will I be able to check that? I'm almost certain I had it seated all the way down.

It's not about seating. It's about rotational alignment. Read in the big OPDA thread.

From your other post you were getting several O2 codes. Did you get them fixed? Weren’t you going to try a new PCM?

I think I read that someone recently thinks he fixed his P0344 with a PCM but maybe too soon to know if it fixed it long term. Being an intermittent code it can come & go & sometimes a new sensor clears the code for a while only to return. Another guy replaced the PCM & it did not fix his P0344 code which returned immediately so who knows. Be sure to check the wiring from the sensor to the PCM including where the harness goes over the oil dipstick bracket.

Usually a rotational misalignment called cam/crank sync will throw a P0016. P0344 is intermittent loss of cam sensor signal to the PCM. But wouldn’t hurt to check it.

Rubi4MyMrs - yes I did put I new PCM in, approximately 2-3 weeks ago, cleared all my O2 codes. Been running fine since, no codes until this morning. No other codes being thrown besides P0344. Used a scanner to clear the code for now and it's ok. I'll run through the wiring and see what I can find. It wouldn't surprise me if I find something... If any of the wiring on it, the conduit just falls apart like everything is dry rotted somehow. My 98 never did that.
