Hyundai Venue (QX): 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) and its resistance is in inverse proportion to the temperature.

•
This system monitors the driving situations through the radar
and the camera. Thus, for a situation out of the sensing range,
the system may not normally operate.
