Kia Cadenza YG: Air Conditioning System / A/C Pressure Transducer Description and Operation
Kia Cadenza YG 2016-2021 Service Manual / Heating,Ventilation, Air Conditioning / Air Conditioning System / A/C Pressure Transducer Description and Operation
| Description |
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.
Component Location
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 or not.
