A failing sensor can show up as the engine running poorly, higher fuel consumption or a lit malfunction indicator light, but those signs have other possible sources too. Before replacing it, find the cause: with the engine off and cool, look over the sensor, wiring harness and connector for physical damage, which can shorten a sensor's life.
