Hyundai Kona: Engine Control System / Ambient Temperature Sensor (ATS) Description and operation

Ambient Temperature Sensor (ATS) is installed on the front-end module and senses the ambient temperature. ECM receives not only the intake air temperatue but also the ambient air temperature informations at the same time to control the intake air quantity precisely provided through the turbo charger. The electrical resistance of the thermistor decreases as the temperature increases, and increases as the temperature decreases This sensor has a Negative Temperature Coefficient (NTC) and its resistance is in inverse proportion to the temperature.
