Dreaded check engine came on and took it to the dealer to find out it is a $400 to replace oxygen sensor with the part. So I told them to go kick rocks and decided to get one at Autozone for $79 instead of $134 at dealer. So does anyone know where Bank 1 side 1 O2 is? And do you need a special tool to get it out or will a standard O2 wrench work? BTW its a 2nd gen.

Bank 1 is the passenger side and sensor 1 is the sensor in the manifold. regular O2 socket shold be fine

Could the 02 sensor really be out ? Maybe you just simply have a bad cat. Mine went retarded at like 29k miles, im at 40k miles and still need to get them replaced, my truck has a dirty title so nissan won't help me, looking to just install Long tube headers.

I just have to go by what the Nissan tech said and replace it for $79 and go from there and see if it goes away.
