Kia Cee'd: Troubleshooting / A/C Pressure Transducer Description and operation

By converted voltage value, engine ECU controls the cooling fan by operating it 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.
