I think that might be the one after the cat. converter?

yes it is the one mounted in the Cat. Converter, but which one, I know some GC (california models) have 4 O2 Sensors and 2 cat converter, 1 Pre, 1 Post for each Cat.. if you have the Federal model it only has 2 O2 Sesnors, 1 Pre Catalytic Converter and 1 post Catalytic Converter (mounted in the rear of the Cat).
Bank 2 Sensor two would be the one in the Cat. ussually when this one fails so does the Catalytic converter.
