I recently had a CEL code of P0133 pulled from my 96 F150, OBD-II which is slow response O2 sensor bank #1. Which side is #1 and which is #2? I assume the left from driver's seat is #1? Can anyone clarify? The gentleman who checked this for me told me the code is bank #1 but I see conflicting code descriptions throughout the forums.

Thanks very much

 

bank #1 on the same side as #1 cylinder.passenger side

 

Thanks very much. I just finished changing it and reseting everything. The drive to work tomorrow will tell the tale I guess.
