A failing sensor can show up as a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness, a loose connector or an exhaust leak can be behind these signs too, so find the cause before buying a sensor. Once the engine is cool, look the sensor, harness and connector over for physical damage.
