The evaporator temperature sensor will detect the evaporator
core temperature and interrupt compressor relay power in order to
prevent evaporator from freezing by excessive cooling
Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between terminals No. 1 and No. 2.
2.
Inspect the voltage value whether it is within the specified range.
