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.

System Overview
Parkin Distance Warning (PDW) is an electronic driving aid that warns the driver
to be cautious while parking or driving at low speed. The sensor uses ultrasonic
waves to detect objects within proximity of the vehicle.
