Re: Please help decipher these codes. Thanks! (dsk888)
I think your pcm was confused because you were on a dyno and the front wheels were not moving.
C 1221 h left front wheel speed sensor is 0
C 1222 h Right front wheel speed sensor is 0
PO200 h I couldn't find anything on this, but it has to do with your ABS brake system, and I think it was just confused.

Had a dyno done a few months ago and the tech told me before we started that the computer would probably throw those codes because of the A/H, TC and ABS. He said not to worry about it, it was normal. Just clear the codes and all should be well. :cheers:
