Bank 1 refers to the location of the bank of cylinders that contain the #1 cylinder. Sensor 2 refers to the Oxygen sensor after the catalytic converter. Bank 1 is the left side of the engine, in this case against the firewall, and Sensor 2 is past the catalytic converter on that bank.
Bank 1 is the side of the engine with the number one cylinder, in your vehicle it is the passengers side. Sensor 1 is the first one coming from the engine, before the catalytic convertor, in the exhaust pipe.
