Question

Answer 1

How long have you driven you Xterra since the last code reset or battery disconnect? Usually completing the Oxegen sensor is not difficult, according to the service manual, you just have to drive your Xterra for about 5 minutes between 50 and 60 MPH. If after a few days of driving, the oxygen sensor monitor still doesn't complete, then you may have to replace the sensor,
