A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, since an exhaust leak can cause similar trouble. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
