The AC evaporator is normally located behind the engine compartment firewall, well positioned behind the edge. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat. When the temperature drops bellow a preset temperature value the compressor magnetic clutch will be turned off, thus stopping the compressor and avoiding damage to it, due to the change in oil viscosity and poor lubrication back to the hvac compressor, because of too low temperature in the system. 2. The evaporator temperature sensor tells the PCM or ECM the temperature of the evaporator and keeps the evaporator core from freezing .It is usually located inside the hvac case underneath the dash, mounted on the evaporator core. It reads and sends the temperature of the water/antifreeze mixture to the gauge. This component is normally installed directly in the AC evaporator, which performs its activity by monitoring the temperature of this component. Answer.
