Is yours the 4 cylinder engine? There should be another number listed. The exhaust system has 2 sensors for each side, or Bank, of the engine. It will be listed as Bank One Sensor One or Bank One Sensor Two. Sensor One is always before the Catalytic Converter, often in the exhaust manifold or the first section of the exhaust. Sensor Two is always after the Catalytic Converter in the exhaust pipe itself. This will be the repeated on both sides of a V6 or V8 engine. A four cylinder engine will have 2 sensors and a 'V' will have 4 sensors.
