A failing sensor can show up as rough running, higher fuel consumption or emissions, or a lit malfunction indicator light. A vacuum leak, an exhaust leak or a worn spark plug can bring on the same signs, so find the cause before buying a sensor. With the engine off and cool, look the sensor, harness and connector over for damage.
