bank one sensor 1 is the bank of cylinders that number 1 spark plug is located in, bank 2 the other side, this assumes u have a V8, the sensor one location is the sensors that are BEFORE THE CATALYTIC CONVERTER, the sensors referred to as sensor 2 are after the ones AFTER THE CATALYTIC CONVERTER IN THE EXHAUST SYSTEM.
