1996 aft O2 sensors

[domer94]

guys , are the aft sensors on a 96 the same part? ive been tring to confirm thi on many autoparts sites but dont have a clear picture. i had a p0161 bank 2 code , so i ordered an Ac delco AFS106 which said aft sensor position 3. there was no position 4 specified , so i am assuming they are the same for bank 1 and 2 aft positions.

thanks

That code is for Bank 2 sensor 2, so that would be the o2 sensor behind your catalytic converter on passenger side
