Bank 2 is on the side of the motor with the #2, #4 and #6 spark plugs, I believe it would be the drivers side 02 sensor before the cat. Matco makes a great tool for hard to access 02 sensors that you use a 3/8 breaker bar with. Before you round the old 02 sensor nut off cut the wire and use a 22mm deep socket or heat with a torch.

Before. This code refers to the front oxygen sensor on Bank 1
