Kia Cadenza: Air Conditioning System / A/C Pressure Transducer Description and Operation
A/C pressure transducer 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.
Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals.
2.
Inspect the voltage value whether it is sufficient to be regular value ...

Wrap tin foil around the end of the voltmeter test lead to
prevent damaging the heater line. Apply finger pressure on the tin foil,
moving the tin foil along the grid line to check for open circuits.
