A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and each of those can have other causes. With the engine off and cool, look over the sensor, its wiring harness and its connector for physical damage before you replace anything, because damage there can shorten a sensor's life too.
