So i got my o2 replaced last friday. on sunday my ses light comes on again. I m sure its the same thing. Anyways... could my failing MAF have anything to do with my o2 sensor? i paid $109 to get mny o2 replaced and i am not going to continue to spend money on a problem that may be reoccurring. thanks.

 

Have you had the TSB performed?

does this tsb mean we get our 02 sensor covered by the 80k warranty? or do we still need to pay like usual....

 

Although I believe the law says 80K, I believe Nissan uses vague terminology to say "only when it fails to comply during an emissions test" or something like that in your Owners' Manual.

So, if you're due for an emissions test soon, hold off and get your failure notice and stick it too Nissan.

Otherwise, you're screwed.
