Hyundai Genesis (DH): 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 at 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.

    Replacement 1. Remove the condenser. 2. Remove the cap (B) on the bottom of the condenser with the L wrench (A). Tightening torque : 9.81 ~ 14.
