I have an 05 Maxima with a 100k/$0 deductible ext warranty. Just about $420 the famus P0420 come up and keeps coming back. It's eather my cats or the rear bank 1 o2 sensor taking a crap. Anybody know if this is covered under warranty? I went to the dealership and was told it would $90 to diognose the problem and only after they would be able to tell me if this is under warranty.. What's yall's take on this?
BTW, the car has 62k miles and even with this p0420 code I am still getting 30+ mpg on hwy..
