A failing sensor might show up as an engine that runs poorly, higher fuel consumption or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, since an exhaust leak or damaged wiring can produce them too. With the engine off and cool, the sensor, harness and connector can be checked for physical damage.
