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  ...

   Compression Pressure Inspection
								   
If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.
1.
Warm up engine until the normal operating temperature(80~95°C(176-203°F)).
2.
Remove the surge tank.
