Outside Temperature Display Sensor: Description and Operation
Operation

OPERATION

The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent by the Front Control Module (FCM). The
resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the FCM. Based upon the resistance in
the sensor, the FCM senses a specific voltage on the temperature sensor signal circuit. The FCM then translates the voltage into a temperature reading
that it sent over the Controller Area Network (CAN) data bus to other modules utilizing temperature information.
