There are four oxygen sensors for this vehicle - two for each bank of cylinders. They are located on the exhaust pipes just ahead of and after the catalytic converters - sometimes referred to as "upstream" and "downstream" of the catalytic converters. Bank 1 refers to the bank of cylinders where cylinder number is located, which is the left or driver's sidde. Sensor 1 is located ahead of (closer to the engine) the catalytic converter. Sensor 2 is located after the converter. The same goes for bank 2.
