A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a misfire could trigger similar symptoms. Look over the sensor, wiring harness and connector for physical damage as well.
