if you have one wire, yours is not heated. If there is more than one wire, like say 3 I think it is, then you are like most of us, with a heated o2.

well i just looked under my hood and the wire(s) are sleeved, i pulled up the sleeve and i saw 3 wires...thin. a red, black, and white one. since i bought the car used, could this be the O2 from courtesy nissan? or does the NX come stock with heated O2?

Stock is heated. The Bosch one I just installed is three wire. The one I pulled out had a nissan symbol on it but the one from the dealership is made by Bosch. $137 at the dealeship $65 at Autozone. Both made by Bosch. Hmmmmmm?

There is no question or doubt, Bosch is the so far the only maker of o2 sensors out there. They make for all the aftermarket and even the factory. There is another brand Echlin from Napa autoparts but it is a bosch lesser brand, works just well.
