Kia Rio: A/C Pressure Transducer Description
The A/C Pressure Transducer (APT) convert the pressure value of high pressure
line into voltage value after measure it. By converted voltage value, engine
ECU controls cooling fan by operating it high speed or low speed. Engine ECU
stop the operation of compressor when the temperature of refrigerant line is
so high or so low irregularly to optimize air conditioning system.
