Evaporator Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: 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.

- 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).
