Evaporator Temperature Sensor / Switch: Testing and Inspection
Evaporator Temperature Sensor
INSPECTION
1. INSPECT COOLER THERMISTOR
a. Measure the resistance of the thermistor.
NOTE:
-
Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
-
When measuring, the sensor temperature must be almost the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph). If the resistance value is not as specified, replace the sensor.
