A failing oxygen sensor can show up as poor running, higher fuel use or a lit malfunction indicator light. Those signs can come from other faults too, so before replacing the sensor, look it over along with the wiring harness and connector for physical damage, with the engine off and cool. If the sensor is the cause, this one replaces it.
