Craig I believe bank 1 is the passenger side. The kid at Autozone told me the opposite. My reading had 2 bad sensors in bank 2. I changed both on the passener side. CEL came on again I went Autozone got the same reading bank 2. I just changed the 2 on the drivers side, now everthing is happy. The truck runs like brand new.

Don't care too much for this topic, but when I see a bully trying to cram their bull**** down someone's throat, I gotta say something... Anyway, problem solved for an 04', but not sure for the 01'. However, I bet it's the same as an 04', which would be:
Upstream (Banks 1 & 2/Front)
Downstream (Banks 3 & 4/Rear)
Upstream (Banks 1 & 2/Front)
Downstream (Banks 3 & 4/Rear)
