NO ONE knows if bank one is the passenger or drivers side?!?! PLEASE, someone must know! I want to replace the oxygen sensor for bank one and don't know which side. I know on most GM vehicles bank 1 is the drivers side. Didn't anyone ever have to replace an oxygen sensor here ever??? Well thanks in advance if someone responds!
Cool! Thanks! I thought I only saw one o2 sensor(pre-cat) down there and it was on the passenger side. I have to look and see if theres another one or not. I changed it out and my check engine light went away for a few days and now it came back. Its throwing a p0171 too lean bank 1 code. I also cleaned the maf. Any ideas or has anyone gone through this and solved it? Thanks!

If you have a pre-cat on both sides you will have a O2 sensor for each one also there is a O2 sensor for the main cat?.
you cleaned the MAF changed the O2 sensor out, you reset the ECU right?
