How to Maintain the Oxygen Sensor on a 3.7L Engine on 2008 Dodge Nitro?

Check that the engine has cooled down before you service the oxygen sensor, so you don't get a burn from parts in the exhaust system. With the vehicle lifted up, disconnect the wire connector from the O2S sensor, be careful not to pull on the wire connected to the sensor. Apply an oxygen sensor tool to unscrew the part, then wash the threads in the exhaust with a suitable tap to ensure they work properly. Don't add grease to the oxygen sensor electrical connector and please don't try to solder the sensor wiring harness.
