That IS the first place I’m looking. I just can’t remember which one was the one I dropped, my mistake. Just wanted to know if anyone knows which sensor is the one that could be responsible for triggering the code PO174 to lean Bank 2. Thanks

 

I think I found the answer and just in case this happens to someone else and does a search they’ll find it here.

PO171 is Lean on bank one. (Driver Side)
PO174 is Lean on bank two. (Passenger Side)

Bank one is on the driver side and Bank two is on the passenger side right? Correct me if I’m wrong. So if I’m only getting PO174 and I’m pretty sure it has to do with a bad O2 sensor wouldn’t that relate to the passenger side O2 sensor. What do some of the more knowledgeable people in here think on that, I’m just making an assumption and hopping I’m right.
