A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem; an exhaust leak near the sensor can throw off the reading too. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
