Should be in exhaust pipe beyond Y junction. I just looked at a Nissan SE.

Thank you so much. I'll go look there. I found the regular 02 sensor with only one wire just before the catalyst converter, but couldn't find the heated one with the extra wires!

I've taken another look, and the only 02 sensor I find is the one I already knew about. It is located between the fork and the catalyst converter. It only has one wire going out of it, and that is not the right 02 sensor, per my error codes. I am looking for the "heated 02 sensor".
