This should be the oxygen sensor after the catalytic converter off of bank 1, which is going to be the manifold on the right side of the engine.
OK - to clarify and correct:

Bank 1 is the bank by the firewall - nearest the passenger compartment.

Sensor 2 is the after cat oxygen sensor on that bank.
