I was driving home last night when i got punched in the face with a CEL. I took my car over to Autozone and got some codes pulled. P0138 and P0139. I know its my O2 sensor, but my question is: are these covered under the 80K Federal Emissions warranty? I know that Nissan is VERY stingy about warranty work. Anyone ever had this done? Also, how much do you think the stealer charges for O2 sensor replacement?

O2 sensors are only warrantied under 3/36 except for 01+ in California Emissions States( NY...etc) where they are covered 3/50 (even though all 01+ are 50 state). I replaced both rear sensors (P1147/1167) and the sensors ran $138 each from the dealer. You can get them cheaper, but I was too lazy to wait for shipping and Autozone and Advance were only a couple of bucks cheaper. IIRC some have said that it runs $400+ for the dealer to replace O2 sensors: http://forums.maxima.org/showthread....highlight=0420 (see post 8).
