Oxygen Sensor

To change the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, first lift the vehicle and unplug the connector HO2S. Pull off the HO2S with the Oxygen Sensor Wrench (J 39194-B). While performing the installation, if the sensor provider for reinstallation, please make sure that threads are covered with anti-seize compound GM P/N 5613695. Thread in the HO2S by using the Oxygen Sensor Wrench (J 39194-B) and tighten it to a torque of 42 N.m (31 lb ft). Finally, link HO2S harness connector and lower the vehicle.

To replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 one needs to lift the vehicle and disengage the connector for the HO2. Users should also remove the HO2S in the presence of the Oxygen Sensor Wrench (J 39194-B). When installing the new sensor, be sure to apply the threads with anti-seize compound GM P/N 5613695 if needed as this compound with the composition of liquid graphite and glass beads, to make the removal easier in the future. Mount the HO2S with the use of Oxygen Sensor Wrench (J 39194-B) and tighten up to 42 N.m (31 lb ft). Lastly, join the HO2S harness connector and lower the vehicle.

The first step when replacing the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 requires a vehicle to be raised to a specific height. First remove the HO2S electrical connector then slowly remove the HO2S from its seat. Insert anti-seize compound P/N 5613695 onto the HO2S threads before reinstallation because the special compound mixture contains graphite and glass beads which helps future sensor removal. Use an anti-seize compound P/N 5613695 on the HO2S threads and tighten it to 41 N.m (30 lb ft). After reattaching the HO2S electrical connector you should lower the vehicle.

In order to replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1, you will need to lift up the vehicle first. Remove the HO2S connector and pull out the HO2S using the Oxygen Sensor Wrench (J 39194-B) and disconnect its connector. Before installation, also if necessary, coat the threads of the new oxygen sensor with the anti-seize compound GM PIN 5613695, because unique anti-seize compound (liquid graphite and glass beads) are used in the cementation of the HO2S for the purpose of ease of future removal. Add the HO2S using an Oxygen Sensor Wrench (J 39194-B) and tighten it to 42 N.m (31 lb."). Lastly, connect the HO2S harness connector and lower the vehicle.

In order to change the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1 first lift the vehicle. Remove the HO2S by disconnecting the connector of the HO2S, this must be done using the Oxygen Sensor Wrench. (J 39194-B). If required, coat the threads of new or service replacement sensor with anti-seize compound GM P/N 5613695, which is made up of liquid graphite and glass beads, for ease of removal in the future. Install the HO2S using the Oxygen Sensor Wrench (J 39194-B) and tighten it to a torque of 42 N.m (31lb. Ft.). Finally, join the HO2S harness connector and lower the vehicle.

Use the Oxygen Sensor Wrench (J 39194-B) to install it.

Apply anti-seize compound P/N 12377953 to the threads.

Use the Oxygen Sensor Wrench (J 39194-B) to install it and tighten it to 42 N.m (31 lb ft).

Coat the threads with anti-seize compound P/N 12377953, or an equivalent if necessary.

Disconnect the connector for the HO2S.

First, raise the vehicle.

Disconnect the connector for the HO2S.
