Question about 2001 Chevrolet Silverado 2500HD
The cam position sensor (or CMP, as GM refers to it) is mounted on the
driver's side of the front timing cover. just below the water pump.
It's a simple change if you can get to it. I am in the process of
changing my water pump at this moment, and it's really easy to see with
the fan. shroud, and water pump out of the way.
As for your crank position sensor (CKP), did you have a dealer run it through the "learn" cycle? I was just looking through my service manual at the CKP info and saw the procedure for calibrating it. If you've been to the dealer to get done, you are aware of it, if not, that could be why you're getting a check engine indication.
The cam position sensor does not need any sort of calibration, just install it and go.
