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