A failing oxygen sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Newer vehicles may also store fault codes in the ECU. Before you replace the sensor, look over the wiring harness and connector for physical damage and rule out other causes of the same symptoms.
