Locations of oxygen sensors on a 1996 chevy c1500 5.7
@symphony2627 best to see and to get to with the vehicle on a lift.
Oxygen sensors bank 1 is any sensor upstream the catalytic converter and bank 2 is downstream. you’ll have one before and one after the catalytic converter. Even so the attached image shows a dual exhaust it also applies to single exhaust but will of course only have two sensors. This video might help you further.
