Kia Rio: Description - Intake Air Temperature Sensor (IATS) - Engine Control System - Engine Control / Fuel System - Kia Rio UB 2012-2020 Service ManualKia Rio: 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.
