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

In order to replace the heated Oxygen Sensor - bank 1 sensor 1, first, lift and support the vehicle. Remove the front propeller shaft from front Differential, in the case the automobile is 4 wheel driven. Take off the connector position assurance (CPA) retainer and disengage the engine wiring harness electrical connector from the ho2s. Take the clip from the ho2s electrical connector clip from the fuel line clip, then take the ho2s. When installing old sensor, one should coat its thread with anti-seize compound gm p/n 12377953 or equivalent. Replace the ho2s and tighten according to the value of 42 nm (31 lb ft). The engine wiring harness electrical connector should be connected to ho2s and the engine wiring harness electrical connector clip should be fixed to the fuel line clip. Finally, install the cpa retainer and reinstall the front propeller shaft to the front Differential if the vehicle had 4wd, after that, lift 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 1 on GMC Yukon?
A:
In order to replace the heated Oxygen Sensor - bank 1 sensor 1, first, lift and support the vehicle. Remove the front propeller shaft from front Differential, in the case the automobile is 4 wheel driven. Take off the connector position assurance (CPA) retainer and disengage the engine wiring harness electrical connector from the ho2s. Take the clip from the ho2s electrical connector clip from the fuel line clip, then take the ho2s. When installing old sensor, one should coat its thread with anti-seize compound gm p/n 12377953 or equivalent. Replace the ho2s and tighten according to the value of 42 nm (31 lb ft). The engine wiring harness electrical connector should be connected to ho2s and the engine wiring harness electrical connector clip should be fixed to the fuel line clip. Finally, install the cpa retainer and reinstall the front propeller shaft to the front Differential if the vehicle had 4wd, after that, lift the vehicle.
