Evaporator Temperature Sensor / Switch: Testing and Inspection

INSPECT A/C EVAPORATOR TEMPERATURE SENSOR










a. Remove the A/C evaporator temperature sensor.
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 almost the same as the ambient temperature.

HINT: As the temperature increases, the resistance decrease.

If the resistance value is not as specified, replace the sensor.
