Hyundai Genesis: 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 at 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.
