Hyundai Ioniq: Engine Control System / Intake Air Temperature Sensor (IATS). Description and operation
Hyundai Ioniq (AE) 2017-2024 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.

Tilt Steering / Telescope Steering
Adjust the steering wheel so it points toward your chest, not toward your face. Make sure you can see the instrument cluster warning lights and gauges. After adjusting, push the steering wheel both up and down to be certain it is locked in position. Always adjust the position of the steering wheel before driving.
WARNING
NEVER adjust the steering wheel while driving. This may cause loss of vehicle control resulting in an accident.
