2002 Nissan Xterra O2 sensor problem

[Dj BobbyB]

Ok here the deal I bought my Xterra the check engine light was on so I went to AutoZone and used the OBD meter i got a P430 Code on Bank 2 its the O2 Sensor but I dont know which one is the top or lower so before we go any further this is what I can tell you the vehicle dosent loose any power when accelerate dose not loose power in going up hill does not idile down when stopped and has no problem taking off tfrom a complete stop could their be a problem in the wiring connected to the o2 sensor ? any Help or ideas

If the code reader doesn't tell you which sensor it is (sensor 01 or sensor 02), you have two choices. You can either go and find a different scanner (preferably one that will let you look at the voltage readings from the sensor), or you can replace but the upstream (sensor 1) and downstream (sensor 2) sensors, and that should solve the problem.

0430 is the sensor after the cat on bank two. That's the driver side on these trucks
