An IAT sensor, also known as an Intake Air Temperature sensor, measures the temperature of the air entering the engine's intake manifold. This information is used by the engine control unit (ECU) to adjust the air-fuel mixture and ignition timing. A faulty IAT sensor can lead to a variety of problems, including:
* Engine hesitation or stalling
* Rough idling
* Decreased fuel efficiency
* Increased emissions
If you are experiencing any of these problems, it is important to have your IAT sensor checked by a qualified mechanic.
