My CES light came on, went to autozone and got P0037 code. I went ahead and bought the a universal o2 sensor. Guy at autozone told me it was the rear sensor. I changed it but my light is still coming up and reading the same thing. Don't know if I'm changing the wrong sensor or not.

Could anyone help me out ? guy said it was Bank 1 sensor 2 that needs to be changed, which one is that ??
thanks

Did you look in the Top 100 Questions thread? It's answered there.

It's also answered in the Nissan DTC thread sticky at the top of this forum.

Bank 1 Sensor 2 is Passenger's side, AFTER Catalytic Converter.

Personally if I were to replace the sensors, I wouldn't do universal ones. Most of those have to be spliced onto your harness. Why not get sensors that plug-and-play just like the OEM ones?

these don't necessarily fit, just did a quick search on amazon, but I added the links so you can see what I'm talking about. Note: the Universal type just has 3 wires that need to be tapped onto the harness. Whereas the OE type has a plug on it.
