Description And Operation

The evaporator temperature sensor is used to measure the temperature of the evaporator for the Heating, Ventilation, and Air Conditioning (HVAC) module. When the evaporator reaches a temperature that is critical for its safety, the HVAC module disables the A/C request - the evaporator temperature sensor on the evaporator temporarily deactivates the compressor if temperature drops to 0°C (32°F), with risk of "frost" on the evaporator.
