Q:

Where is an IAT sensor located in a vehicle?

A:

The location of an IAT sensor in a vehicle can vary from inside the intake air tube, located between the throttle body and the air filter box, to inside a mass air flow sensor. Other locations could also include inside the MAP sensor or an air mass meter.

An IAT sensor is used to generate an input signal that helps an engine control unit to calculate how much air mass volume is needed for any air change. This sensor also helps manage fuel requirements for the engine as air temperature changes. The IAT sensor is becoming more important in controlling the emission levels of a car.
