A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit check engine light. These signs alone do not prove the sensor is the problem, since an exhaust leak can cause some of them too. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
