A failing sensor can show up as a rough idle, hesitation under throttle or a check engine light. A vacuum leak, a dirty air filter or a damaged wire or connector in the intake and electrical system can be behind those signs too, so track down the cause before you buy. If the sensor is the cause, this one replaces it, and each engine takes one.
