A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. These signs alone do not prove the sensor is at fault, since an exhaust leak can also upset the readings. With the exhaust cool, check the sensor, wiring harness and connector for physical damage.
