Intake Air Temperature Sensor: Description and Operation
Intake Manifold Upper Section
The Intake Air Temperature (IAT) Sensor is located in the upper section of the intake manifold (# 9 in image).
The intake air temperature sensor is an NTC resistor. The electrical resistance of the sensor decreases as air temperature increases. The engine air
temperature signal is used by the Motronic control module for ignition timing, idle speed control and fuel injection quantity.
