Question

Quizplus · Accepted Answer

The IAT sensor can be an integral part of the MAF sensor in some vehicle designs, providing temperature data along with airflow information. In other designs, the IAT sensor is a separate, discrete component located in the intake air passages or air cleaner assembly to measure the temperature of the air entering the engine.
