I hooked the Torque App up and ran several tests while driving.

I got one occurrence of [tid: $46 cid: $05], no label.

I have no idea what this means, but I think it may be a lean on cylinder #5?

and several occurrences of tid: [$03 cid: $44], Low Sensor voltage for switch time calculation.

I'm going to guess that the low voltage reading is to the tcc, since that's the SES code that the ECM is giving me. Not positive though.
