Well another sensor went, so just to be absolutely thorough in my documentation of these things, I thought I'd make a new post to help other confused people out in the future.
O2 Sensor CEL Codes:
P0051 - Bank 2 Sensor 1 Sensor
P0031 - Bank 1 Sensor 1 Sensor
P0134 - Bank 1 Sensor 1 Wiring Harness (included in below listed part number)
O2 Sensor Locations:
Bank 1 Sensor 1 - Passenger Side Pre-Cat Sensor
Bank 2 Sensor 1 - Driver Side Pre-Cat Sensor
Bank 1 Sensor 1 & Bank 2 Sensor 1 Replacement Part No.: 22641AA03C
I'm sure there's others out there that like to see this information in black and white for verification, and this thread seems to come up pretty high in Google when searching for H6 O2 sensor locations.
