Kia Carens: Air conditioning System / A/C Pressure Transducer Description and operation
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 high speed or low speed. Engine
ECU stops the operation of the compressor when the temperature of refrigerant
line is very high or very low irregularly to optimize air conditioning system.
