Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: INSPECTION

1. INSPECT EVAPORATOR TEMPERATURE SENSOR

(a) Measure the resistance of the sensor.





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

If the result is not as specified, replace the sensor.
