This engine uses the ign. Coil pulses to determine cam position, hence the cam position sensor code.
If the code comes back, and the plugs and wires are older, I'd replace then with ac delco ones.
Also, Isolate the wire from the ignition module to the PCM. ( Run new wire). The wire may be picking up something from one of the fuel injector wires in the harness.
