A check engine light, a rough idle or poor fuel economy can mean the sensor is worn, though a wiring or exhaust fault can show up the same way. Before you replace it, look over the sensor wiring and connector for damage with the engine off and cool, and have a shop test it if nothing shows. This listing is one sensor for the rear, center position, and these cars take one in that spot.
