A failing oxygen sensor can show up as a check engine light, rough running or higher fuel use, but those signs can have other origins, such as damaged wiring or an exhaust leak. Before replacing the sensor, look over its wiring and connector for chafing or damage with the engine off and cool. A shop can test the sensor signal itself.
