How to replace the Intake Air Temperature (IAT) sensor on Chevrolet Trailblazer?

The Intake Manifold Temperature Sensor is a thermistor. This sensor changes its resistance values in correspondence with temperature. As the sensor's temperature increases, the sensor's resistance values decrease. On the contrary, as the sensor's temperature decreases, the resistance values of the sensor increase. First, remove the electrical connector to replace an Intake Manifold Temperature Sensor. Second, twist and pull out the unit from the air intake duct. The installation process is simple- just do opposite steps of the removal process.
