A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the 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. Look the sensor, wiring harness and connector over for physical damage.
