Oxygen Sensors: When To Replace
My 2004 Civic LX Coupe has two oxygen sensors, a "downstream" sensor and an "air/fuel" sensor (upstream). Neither sensor is mentiioned in the Maintenance Schedule at all. Is there no recommended interval for replacing these things? Are you supposed to just wait until a fault code pops up to replace them?
