On a 2001 Pathfinder SE 3.5L,

My OBD II sensor says the "Bank 2 Sensor 2" has failed and is the reason my Check engine light is on. It came on after the wrong Fuel Spec (87 octane) was put in. Is it the passenger side or driver side and before or after the converter.

Thanks,

C Hentz

SPEEDO

I hate when they put it that way....... I believe the right side (pass side) would be bank 2 and sensor 2 is the rear one on that side. If I remember right that one should have a white wire

What did you do to fix it and what did it cost you? I checked online and a new o2 sensor is around $150.

I hard wired a three wire universal oxygen sensor and reset the code. It was the Right rear. Yours may be a 4 wire though. It is exactly like wiring a speaker together. Cut splice.

Thanks,

Chuck
