This too is a thermistor, the IAT sensor changes voltage accordingly to ambient air temperature, the EEC uses this information mostly to change fuel delivery when the engine is cold at startup. The sensor is located inside the Intake air duct.

To clean and inspect the IAT, remove and look for dirt or oil. Clean the sensor with isopropyl alcohol. If the sensor still fails, replace the unit.

Codes 112 to 114 will set a IAT/ACT sensor code.
