A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a check engine light. Several other faults produce these symptoms too, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage first. If a failed sensor is the cause, this one replaces it.
