Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: INSPECTION

1. INSPECT EVAPORATOR TEMPERATURE SENSOR

(a) Disconnect the evaporator temperature sensor connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NOTICE:
* 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 the same as the ambient temperature.
HINT
As the temperature increases, the resistance decreases (see the graph).
