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