Kia Sportage: Engine Control System / Intake Air Temperature Sensor (IATS) Description and operation
Intake Air Temperature Sensor (IATS) is included inside Manifold Absolute Pressure
Sensor and detects the intake air temperature.
To calculate precise air quantity, correction of the air temperature is needed
because air density varies according to the temperature. So the ECM uses not
only MAPS signal but also IATS signal. This sensor has a Negative Temperature
Coefficient (NTC) Thermister and it's resistance changes in reverse proportion
to the temperature.
