Old thread on Nissan Sentra 1.8 O2 sensor replacement. Posted this on that thread but probably won't get seen so posting here.
After battery reset and new O2 upstream the check engine light came back on. I get 2 codes. One is EVAP (Po455 8) and may be due to the gas cap not seeming to fit correctly. New gas cap ordered.
Second code is P2A00 0 Bank 1 which is 02. My gas mileage is 31 mix and 35 highway so it's working. Before the new O2 it was around 18 MPG mixed driving. Bank 1 is upstream and Bank 2 would be the downstream O2 correct?
Surprisingly there were no other codes on the complete scan. I figured there would be a few!
