Intake Air Temperature Sensor

The Intake Air Temperature (IAT) sensor inputs air temperature to the PCM. The IAT sensor changes resistance in response to air temperature. The IAT sensor resistance decreases as air temperature increases. For the IAT sensor location, see IAT SENSOR LOCATIONS  table.
