FAQ for Oxygen Sensor Repair
Q: How do you install the Heated Oxygen Sensor-Bank 1 Sensor 1?
A:
If reinstalling the old sensor, coat the threads with anti-seize compound GM P/N 12377953, or equivalent. You need to install the HO2S, connect the engine wiring harness electrical connector to the HO2S and install the engine wiring harness electrical connector clip to the fuel line clip, the CPA retainer, and the front propeller shaft to the front differential, if equipped with 4WD.

02/11/2022Q: What should be noticed when servicing the Heated Oxygen Sensor?
A:
You can not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor causing poor performance. You can not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems. You need to ensure the sensor or vehicle lead wires are not bent sharply or kinked and sharp bends or kinks could block the reference air path through the lead wire. You can not remove or defeat the oxygen sensor ground wire, where applicable. Vehicles that utilize the ground-wired sensor may rely on this ground as the only ground contact with the sensor. Removal of the ground wire will cause poor engine performance. Then you need to ensure that the peripheral seal remains intact on the vehicle harness connector to prevent damage due to water intrusion.
