A failing oxygen sensor can show up as a check engine light, rough running or poorer fuel economy, but those signs can have other causes too. With the engine off and cool, look over the sensor's wiring and connector for melted insulation or damage, and find the cause before you replace it. If the sensor is the cause, this one replaces it.
