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