Front Evaporator Temperature Sensor - Description
DESCRIPTION
NOTE: Cutaway view of HVAC housing shown for clarity.
The evaporator temperature sensor (1) measures the temperature of the conditioned air downstream of the A/C evaporator (2). The evaporator temperature sensor is an electrical thermistor within a molded plastic case that is inserted into the HVAC housing (3) near the coldest point of the A/C evaporator. Two terminals within the connector receptacle (4) connect the sensor to the vehicle electrical system.
The external location of the evaporator temperature sensor allows the sensor to be removed and installed without disturbing the refrigerant in the A/C system.
