A failing sensor can make the engine run poorly, burn more fuel, raise emissions or turn on the malfunction indicator light. A damaged wiring harness or connector, or another engine fault, can produce those signs too, so find the cause before you buy a sensor. Looking the sensor, harness and connector over for physical damage is a good first step.
