Hyundai Santa Fe: Intake Air Temperature Sensor (IATS). Description and Operation
Description
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.
