Intermittent P0344 with P0622

[AllenTC2]

I keep getting a check engine light with a P0344 code. Comes on for a day or two, then goes out. But to keep it fresh, when I make a sharp right turn while getting on the throttle, the check gauges light comes one, the LJ gives a lurch, and it sorta acts like limp mode. THAT gives me a 0622 code. Pulling over, turning the engine off, then restarting makes the check gauges light go off.

I have a Crown OPDA with the OEM cam position sensor. I am HOPING it's just a bad sensor (though I am having a Devil of a time finding a Mopar replacement).

Any other ideas of what I should look at?

You probably have two separate issues but P0622 is most likely because the field wire is shorting to ground. It’s possible P0344 is also due to a short.

Both wires essentially follow the same path to the PCM. Take a look at the wiring harness, starting where it runs over the dip stick bracket. You may also want to pull the coil pack to check where the harness runs up the engine block.

I'm guessing this is where you mean about the dipstick bracket? It IS rubbing against it but it doesn't look like it's gotten through the wire sheath.

Right now P0622 is intermittent because the exposed wire is only touching ground when the engine mounts flex. This will get to a point where the wire is constantly touching.

You need to dig deeper. Pull the coil rail and inspect the loom as I suggested previously. Your field wire is shorting to ground somewhere between the alternator and the PCM. This also increases the possibility that P0344 is also a short.

I can't stress this enough, seriously.

@AllenTC2, you need to pull things apart and very, very thoroughly inspect the wiring. There is a very good chance this is your problem.

Will do....gotta go slow, I'm not exactly mechanical inclined. LOL
