swartlkk,
Thank you It seems that the Harness to the pcm was loose. I cleared the codes -reinserted the harness of wires to the pcm ,ensured they were tight and the codes toe the 122 and 102 were gone. Go figure.. I know I did do work replacing the blower motor what a joke on this truck that was! Where was chevys head on that on!

Glad you got the codes taken care of. Lets hope that sticks.
On the blower motor... Well... I am sure that if they had put it someplace else, it would cause someone else to have a problem with another related item...

I know this sounds silly but i chased this code forever. Check fuse three or four on drivers side of dash. Mine was blown replaced several times before i found the short. Broken lh motor mount = broken tranny mount = after cat o2 sensor hitting the floor. I replaced o2 sensor and have never had a po102 since. Good luck also i have four page wiring diagram.
