Kia Sedona: Intake Air Temperature Sensor (IATS) Description and Operation
Third generation YP (2014-2025) / Kia Sedona YP Service Manual / Engine Control / Fuel System / Engine Control System / Intake Air Temperature Sensor (IATS) Description and Operation
| Description |
Integrated into the Barometric Pressure Sensor (BPS), the
Intake Air Temperature Sensor (IATS) 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 BPS signal but also IATS signal.
This sensor has a Negative Temperature Coefficient (NTC) thermistor and
it''s resistance changes in reverse proportion to the temperature.

In the event of brake failure
If service brakes fail to operate while the vehicle is in motion, you can make
an emergency stop with the parking brake. The stopping distance, however, will be
much greater than normal.
