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.

Chevrolet Colorado Mass Air Flow Sensor

MAF in Chevrolet Colorado is among the important components as it provides the information regarding air mass flow that enters the engine in order to control the fuel consumption and, therefore, the performance of the vehicle. The Lambda sensor sends this data to the engine control unit (ECU) that then offsets the air to fuel ratio with the current load and acceleration. Chevrolet Colorado models have used the following Mass Air Flow sensors at some point: Vane Meter and Hot Wire sensors. The Vane Meter used a mechanical air vane that may hinder airflow and possibly degrade with use, but the Hot Wire sensor has an improved accuracy through current fluctuation on a heated wire. Other versions of the technology include Hot Film and Coldwire sensors, which work in fundamentally different ways, but are designed to offer the same level of airflow accuracy. Maintenance should be done for every other time to avoid contamination to the Mass Air Flow Sensor in Chevrolet Colorado vehicles' functioning and longevity.

Each OEM Chevrolet Colorado 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.
