Evaporator Temperature Sensor / Switch: Testing and Inspection

INSPECTION

1. INSPECT EVAPORATOR TEMPERATURE SENSOR







a. Measure the resistance of the sensor.

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 decreases (see the graph).

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