Default pcm problem??

Is it common for a pcm to go bad?
My friend scanned my truck with his snap-on solus and it came up unable to complete scan 4 times. I am having a problem that no one can seem to figure out.
When cold my truck starts and idles fine, but when you try to drive it it throws codes for bank 1&2 timing over retarded, and bank 1&2 cam sensor circuit malfunction. It acts worse after its warmed up.
Checked everything imaginable.

My question is has anyone had a power train control module fail and what did it act like?

No, it is not common for the PCM to go bad. Is your friend connecting the tool to the OBDII connector under the steering wheel (to the right)? If so, the fuse may have blown that powers this connector plus the accessory plug (cigarrette lighter).

Fuse #41 is what I would check first.

We were using the obd 2 port under the dash. It was running a test and you could hear things happening under the hood. It would always say unable to complete scan after a couple of minutes. It did pull a code p0345 which was already on there.

thanks for the suggestion.

I am towing to the dealer on Tuesday. They will do a pcm check and update for $85.

Pcm was fine. Cat on the drivers side was plugged. Still runs like crap with that fixed so I am going to check the injectors next.
