Kia Optima: 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.
