A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can be behind those same symptoms, so look both over for physical damage while the engine is off and cool, and find the actual cause before you buy a sensor.
