You apparently have a bad connection or wire. I presume you are setting P0341.

The basic diagnostics are to probe the wire and its connection to the pcm or to the sensor itself.

You can try and run a jumper wire from the 12 volt signal from the pcm to the cam sensor to bypass any short in the wire loom itself. Also make certain that you didn't have damage on the sensor connector itself. Also if the cam sensor is actually touching the reluctor wheel it will set the code.

Pretty much get back there and check the sensor, its connector and the wire to the pcm. Since you were pulling the heads I would suspect the sensor side ofthe circuit for a problem.
