Hyundai Elantra: Air Conditioning System / A/C Pressure Transducer Description and Operation

Hyundai Elantra AD (2016-2020) Service Manual / Heating, Ventilation and Air Conditioning / Air Conditioning System / A/C Pressure Transducer Description and Operation

Description

The A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. 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.
