What are the functions and precautions for oxygen sensors in Chevrolet Colorado and GMC Canyon?

Two oxygen sensors are equipped by every model, the pre-converter oxygen sensor and the post-converter oxygen sensor. The voltage output of the pre-converter oxygen sensor is affected by a variety of factors, including the amount of remaining oxygen in exhaust gases after combustion. The PCM constantly monitors this signal to determine fuel injector pulse width requirements and maintain a 14.7:1 air/fuel ratio. On the other hand, post-catalyst O2 sensors do not affect mixture control but their signals are used by the PCM to monitor catalyst efficiency. To work properly they require correctly wired electric circuits, ventilation, operating temperature and lead-free petrol. If any sensor problem is detected by PCM it uses diagnostic trouble codes to set open-loop fuel control mode. When replacing an O2 sensor one should be careful not to damage it or its electrical connector. The post converter one might necessitate raising the vehicle while pre-catalyst can be changed without raising it up. A ratchet wrench or socket that fits must be used to remove the sensored spark plug as well as coating threads with anti-seize compound before installation is done; after which connecting electrical connector is necessary before lowering down vehicle all these are completed successfully.

GMC Canyon Oxygen Sensor

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.

Each OEM GMC Canyon Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
