    Q:
    How to replace the Heated Oxygen Sensor - Bank 1 Sensor 2 on GMC Yukon? Posted by Customer
    A:
    To replace the Heated Oxygen Sensor - Bank 1 Sensor 2, you would first have to lift and support the vehicle. If for the 2 wheel drive (2WD) models, then remove the connector position assurance (CPA) retainer to disconnect the HO2S electrical connector from the engine wiring harness electrical connector. Skip for 4 wheel drive (4WD) vehicles. The CPA retainer needs to be removed along with the HO2S electrical connector that should be disconnected from the engine wiring harness electrical connector. Carefully remove the HO2S. When installing the old sensor, the threads should be coated with anti-seize compound GM P/N12377953 or equivalent, since special anti-seize compound is used on the HO2S threads in order to facilitate future removal. Install the HO2S and tighten it to 42 Nm (31 lb ft). In case of 4WD models, connect the HO2S electrical connector to the engine wiring harness electrical connector and install the CPA retainer. Then link the HO2S electrical connector to the engine wiring harness electrical connector and replace the CPA retainer again. Finally, lower the vehicle.

    Q:
    How to replace the Heated Oxygen Sensor - Bank 2 Sensor 2 on GMC Yukon? Posted by Customer
    A:
    Vehicle elevation and support starts the procedure of Heated Oxygen Sensor - Bank 2 Sensor 2 replacement. First disconnect the HO2S electrical connector from the engine wiring harness electrical connector along with the removal of the connector position assurance (CPA) retainer. Carefully remove the HO2S . The use of anti-seize compound GM P/N 12377953 or equivalent is recommended to coat sensor threads when reusing the same sensor because the HO2S threads require a special liquid graphite and glass bead blend that makes future uninstallations easier. Affix the HO2S and fasten it to a torque of 42 Nm (31 lb ft). The vehicle section requires installation of the CPA retainer after connecting the HO2S electrical connector to the engine wiring harness electrical connector.
