Bank 1 is your upstream O2 sensor. Usually located in the exhaust manifold. This sensor monitors exhaust gases & tells the computer what's coming out of the engine. The computer uses that information to make constant adjustments to maintain the proper air/fuel mixture for optimum performance & emission control under all driving conditions. Bank 2 O2 sensor is located in the exhaust pipe just after the catalytic converter. Also called the downstream O2 sensor its job is to monitor the catalytic converter. If your computer tests the catalytic converter & it fails it is the downstream O2 sensor that picks up on it & sets a trouble code to alert you the catalytic converter is bad. HTH. -Jim
