just a quick note: bank 2 is LEFT side (drivers) on a rear wheel drive vehicle ,on front wheel drive vehicles it would be the front side when looking down from the front of the vehicle ,Sensor 2 is after the cat converter! if you replace that sensor, clear the codes or have someone clear them for you and you should be all set

Hey James==It would help if you stated what kind of car you have. Joe
the 2 of bank 2 is the 2nd oxygen sensor that is located after the catalytic converter.usually closer to the tailend of the header pipe.
The sensor I believe you are looking for is in the exhaust pipe or exhaust manifold, usually the right bank which is on the right side of the car (driver is left), or close to the firewall if engine is mounted sideways. Some cars are equipped with a sensor behind the catalytic converter that tells the computer the HEALTH of the converter only. It has nothing to do with running of the engine per say.

Bank 1 is which ever side has cylinder 1. It could be left or right. Bank 2 would be the other side. Bank 1 sensor 1 would be before the catalytic converter. Bank 1 sensor 2 would be after the converter. The same applies with bank 2.

This is referring to the first Oxygen sensor, located on the exhaust manifold. It either indicates a short in the wiring or the sensor needs to be replaced altogether.
