A failing sensor can make the engine run poorly, burn more fuel or turn on the malfunction indicator light, and newer cars may store a related fault code. Those signs can come from other causes too, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace it.
