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

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.
