What is the function of the Intake Air Temperature (IAT) sensor and Mass Air Flow Sensor and how to replace?

The Intake Manifold Temperature (IMT) sensor is a thermistor, and it changes its resistance according to the temperature. The change in resistance directly affects the voltage signal supplied by the sensor to the PCM. Resistance values decrease as sensor temperature rises and increase when it falls. The IMT is part of the Mass Air Flow sensor, which measures air quantity entering the engine using a hot-wire sensing element. This wire gets cooled as air moves over it. This thermal variation is converted into an analog voltage signal to PCM that adjusts fuel injector pulse width corresponding with airflow. The MAF/IMT can be found on the intake air duct. To replace it, disconnect the sensor electrical connector, remove the two mounting screws and pull the sensor out from the air intake duct. Installation is simply reversing of removal.

GMC Canyon Mass Air Flow Sensor

Mass Air Flow Sensor, or commonly known as MAF, is used in GMC Canyon cars to monitor the volume of air that gets into the engine. This information is sent to the PCM and the latter is responsible for the alteration of fuel injector timing so as to maintain the correct air-fuel mixture for combustion. GMC Canyon has incorporated differing varieties of MAF sensors as Vane Meter (VAF) and Hot Wire. Despite its effectiveness, for instance, the VAF sensor tends to limit airflow and is prone to mechanical wear. The Hot Wire sensor on the other hand is considered to yield more accuracy and flexibility and can be easily influenced by contaminants. There are other types of sensors too, some of them include Hot Film and Karman vortex sensors and although they are quite different from the working principle from that of the other types mentioned above, they are used in similar applications, that of airflow measurement. In order to ensure a proper functioning of the Mass Air Flow Sensor in a GMC Canyon, maintenance should be done regularly.

Each OEM GMC Canyon Mass Air Flow 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.
