Question about Nissan Xterra
2006 Nissan Xterra keeps throwing code for bank1/sensor1. I replaced it, and the light came back on within an hour. The code was the same. I took sensor back to auto store thinking it was faulty. Replaced it yet again. Same thing. Same code...... not too sure where to go from here!
You are lucky they took it back. Did you use the proper wrench to install it and use the proper anti-seize lubrication? Check the wiring to it all the way that you can. IT would be best if you could check it all the way to the ECM. Do you remember what the code was?

Hi,first thing your cambelt and tensioner should have been replaced 13k miles ago,it would pay you to replace the water pump at the same time as they are known for impellor failure = cooling system fault=P2181 code,hope this helps.

It is a good idea if replacing one 02 Sensor to replace all of them at the same time. Location is- they screw into the exhaust pipes below the exhaust manifolds and before the muffler.( Very hard to miss them ). Make sure you have the codes cleared from the on board computers memory after repairs are finished. Good Luck and have a good XMASS,

if you have an O2 sensor faliure you will have a code for it. in fact youe exterra doesnt have O2 sensors. it has A/F sensor or "air/fuel sensor" if it went bad, than you will have a code for that sensor. What is the code number that you have?? need to start there.
