How to replace the Heated Oxygen Sensor (HO2S) 2 on GMC Canyon?

The replacement of heated Oxygen Sensor (HO2S) 2 requires a vehicle lift and supportive base. The Engine Wiring Harness Connector needs its ho2s electrical connector removed. Remove the ho2s from its Catalytic Converter position by using the heated Oxygen Sensor wrench (J 39194-B). Before installing an ho2s you must apply special anti-seize compound on its threads because this compound consists of graphite suspended in fluid and glass beads. The threads of the same sensor should receive anti-seize compound before a new installation occurs. Before installation apply anti-seize compound p/n 5613695 (or equivalent) on the ho2s threads. Place the ho2s into the Catalytic Converter and use heated Oxygen Sensor wrench (J 39194-B) to tighten its threads to 42 n.m (31 lb ft). To complete the installation connect the ho2s electrical connector to the Engine Wiring Harness Connector before lowering the vehicle. Using a scan tool to perform a code clear reset of the ho2s resistance learned value is essential to avoid ho2s failure but failure to do so will result in an ho2s failure.

The Oxygen Sensor in GMC Canyon vehicles is necessary for the proper measurement of the air/fuel mixture of the engine exhaust to accomplish optimal performance and emissions. Oxygen remaining unburned is sensed and the detected amount is compared against the ambient level to create a voltage signal that directs the operation of the engine control computer towards the right mixture. Original Equipment GMC Canyon Oxygen Sensors commonly include zirconium dioxide sensing element with platinum layer, enshrouded in ceramic and encased in steel. These sensors employ response temperature and have a heating component for greater reaction rates. Late model Canyon vehicles have a minimum of two oxygen sensors before the catalytic converter and after it to feed the fuel management system. The first sensor is an upstream sensor the second sensor is a downstream sensor that functions to assess the working efficiency of the catalytic converter. Sensors get deteriorated over time or due to contamination and this affects the efficiency of the engine that emits high amounts of fuel. Newer vehicles may use air/fuel ratio sensors instead of the oxygen sensors which enable wider range of accurate measurements. The oxygen sensor is among the vehicle's vital parts that require consistent upkeep and checking of its functionality to enhance the performance as well as the emission quota of the vehicle.
