Evaporator Temperature Sensor / Switch: Description and Operation
Front Evaporator Temperature Sensor - Description
DESCRIPTION
The evaporator temperature sensor (1) is an electrical thermistor located within a molded plastic case that is inserted into the HVAC housing (2) to
measure the temperature of the conditioned air downstream of the A/C evaporator (3). Two terminals within the connector receptacle connect the sensor
to the vehicle electrical system through a wire lead and connector of the HVAC wire harness.
NOTE: Cutaway of typical HVAC housing shown for clarity in illustration.
The external location of the evaporator temperature sensor allows the sensor to be removed or installed without disturbing the refrigerant in the A/C
system.
