Evaporator Temperature Sensor / Switch: Testing and Inspection

INSPECT THERMISTOR RESISTANCE
a. Remove the A/C evaporator temperature sensor (cooler thermistor No.1).
b. Measure the resistance according to the value(s) in the table.

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 the same as the ambient temperature.

Cooling Unit:

HINT: As the temperature increases, the resistance decreases (see the graph).

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