Cleaning O2 sensor S70

posted by  someone claiming to be Helper on  Mon Feb 28 12:08 CST 2005 [RELATED]

To check the sensors first disconnect and inspect the wiring, remove the sensors and clean them, don't use any type of chemicals to do this, the cleaning should be done by using a PROPANE TORCH, place the sensor tip inside the propane flame for a few seconds at a time until all contaminants get evaporated by the heat. Place the sensors back in place. Remember to put anti-sieze paste on the threads and NOT on the sensor.
