Description |
The evaporator temperature sensor detects the evaporator core temperature and interrupts compressor relay power in order to prevent evaporator from freezing by excessive cooling.
Inspection |
1. |
Turn the ignition switch OFF. |
2. |
Disconnect the evaporator temperature sensor connector. |
3. |
Measure resistance between terminals “+” and “-” of the evaporator temperature sensor.
