    Description The A/C Pressure Transducer (APT) converts the pressure value of high-pressure line into voltage value after measuring it. By converted voltage value, engine ECU controls the cooling fan by operating it at high speed or low speed.

    Description The evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing due to excessive cooling.
