Bank 1 & Bank 2

[TuBlaz]

I know there are 3 O2 sensors on my 1995 Maxima. Which side is bank 1, and which side is bank 2 (Driver's or passenger's)?

Thanks in advance,

Bank one would be the most forward one. Bank 2 would be the one closer to the firewall, and the third one is in your cat. When I got my codes for mine they were front or rear. Hopefully that helps.
