How to replace the Heated Oxygen Sensor - Bank 1 Sensor 2 on GMC Yukon?

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.

The Oxygen Sensor in GMC Yukon vehicles is vital in determining the amount of unburned oxygen in the exhaust; this is used to enhance the air-fuel mixture and cut on emission. The sensor creates a voltage signal proportional to the oxygen concentration and the signal is then used by the engine control computer to adjust the fuel injector timing. Contemporary Yukons come with two, or, depending on the powertrain, four oxygen sensors, with the upstream sensors delivering primary data for immediate optimization. GMC Yukons come equipped with oxygen sensors made from zirconium dioxide and, possibly, both narrow-band and wideband sensors. The narrow-band sensors produce voltage signal that indicating from rich to lean condition and the wide-band sensors give wider voltage indication for better air-fuel ratio control. Oxygen sensors can also get contaminated over time because of which emission levels and fuel consumption will improve. Outright checks on performance alongside certain recommended policies such as emission standards' compliance require a regular schedule of maintenance.

Q: How to replace the Heated Oxygen Sensor - Bank 1 Sensor 2 on GMC Yukon?
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.
