OYEAUTO Oxygen O2 Sensor Upstream & Downstream 4pcs for Ford Jaguar Lincoln Mazda Mercury

The oxygen sensor is one of the most critical sensors in your car, as it communicates with your vehicle's electronic control unit (ECU) to help determine the optimal air-to-fuel ratio for the best engine performance. Replacing worn or failed oxygen sensors is the best way to protect expensive three-way catalysts or catalytic converters. Failure to replace failed oxygen sensors at the earliest sign of a problem, usually indicated by an illuminated check engine light, can cause premature failure of expensive three-way catalysts or catalytic converters.

Some common bad oxygen sensor symptoms include failed emission tests, misfiring, rough idling, or stalling, sluggish engine performance, decreased gas mileage, and a flashing check engine light. Common oxygen sensor fault codes include P0175 (system too rich, bank 2), P0713 (fuel trim malfunction, bank 2), P0171 (system too lean, bank 1), P0162 (O2 sensor circuit malfunction, bank 2, sensor 3), and P0135 (oxygen sensor in front of the catalytic converter 1, heating circuit/open).
