Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: INSPECTION

1. INSPECT COOLER THERMISTOR SENSOR

(a) Check the resistance.





(1) Measure the resistance and check the results in accordance with the values in the table below.

Standard:









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

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 on the left).
