A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or switch on the malfunction indicator light, and newer vehicles may store related fault codes in the ECU. Before you replace the sensor, look its wiring harness and connector over for physical damage and rule out other causes of the poor running.
