Q: What should be noticed when servicing the heated oxygen sensor?
A:
You should not apply contact cleaner or other materials to the sensor or vehicle harness connectors. You should not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed. You should not remove or defeat the oxygen sensor ground wire, where applicable. You should ensure that the peripheral seal remains intact on the vehicle harness connector to prevent damage due to water intrusion.
