I have a 98 GXE, and every several thousand miles I throw the same code 04 09. Which is the O2 sensor on the rear (closest to fire wall) branch of the Y-Pipe...someone please correct me if I am changing the wrong one. I have now replaced the sensor twice since I have had the car and I have only put about 40K on the car. Am I changing the proper O2 sensor for this code..and if so what in the heck is causing this problem? Also when I replace the sensor I have always used the Bosch OEM. Thanks for your help.

Maybe the harness is bad.

Call Nissan and see if your Emission warranty is still valid. Might be your computer

well i got my obd2 scanner today and i checked the code and it ended up being p0153 which is 0413 on the cel method....i also checked the readings on the bank 1 sensor 1 and it was all screwed up so i think i found the cause of the cel but i dont know y the cel method was giving me 0409 instead of 0413....very weird hopefully when i change this sensor no more cel

is there some sort of re call for this? I dont have any sort of warranty left on my car that I am aware of.
