Bank1 is the driver side of the engine, senor 1 is on the engine side of the catalytic converter in the exhaust flow.
Just locate the connector with the white cable, in the front of the Engine and it lead you to the oxygen sensor. It has to be attached to the Pre- Cat
It is the Oxygen sensor behind the catalytic converter.
P0133 Means the Bank1 Sensor 1 oxygen sensor is not communicating correctly with the computer, weather the sensor is failing, or there is an issue with the wire/connection from the main harness to the the sensor lead itself. usually replacing the oxygen sensor (this one is located just off the engine in the exhaust manifold) will resolve the issue.
