Search the 2GS forum for "Oxygen Location", I posted full pics to another thread. The thread is called "Pics Of Location Of Oxygen Sensors"

You are very welcome!

Where each sensor is at is dependent on what engine your car has. Refer to the pics. They make it much easier to visualize.

No, the bank refers to the placement of the exhaust manifold on the head or in the engine configuration.

The sensor number refers to it's placement in the manifold. Sensor one is upstream of the catalytic converter or closer to the engine block. Sensor 2 is downstream of the cat, closer to the muffler....
