How to Maintain and Fix an Oxygen Sensor on 2008 Dodge Ram 3500?

Before touching an oxygen sensor for service or repair, give the engine time to cool, since these parts may be extremely hot after running. Lift the vehicle, disconnect the sensor's wire connector once it is supported and try not to stress the wire attached to the sensor. Uninstall the O2S sensor using the proper tool, then use a specific tap to clean up any dirt inside the exhaust pipe's threads. You should not smear grease on the connector or the sensor's wiring harness.
