Where are the oxygen sensors located? on 2000 Saturn LS2

After running an engine code analyzer it says the engine is running rich on bank 2 - an O2 sensor. I need to know where they are located.

why dont you have a diag done on it first. a free code pull is not a diag. most likely, something else is causing the issue and the o2 cannot compensate for the needed readings. Roy
