Kia Optima Hybrid: Engine Control System / Intake Air Temperature Sensor (IATS) Description and Operation

Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Engine Control/Fuel System / Engine Control System / 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.
