Description And Operation

Ambient Temperature Sensor (ATS) is installed on the front-end module and senses the ambient temperature.

This sensor is exposed to the ambient air temperature in front of the radiator.

The ATS is a Negative Temperature Coefficient (NTC)-type sensor and its resistance is in inverse proportion to the temperature.
