Hyundai Genesis: Air Conditioning System / A/C Pressure Transducer Description and Operation
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 ~ 14.71 N.m (1.0 ~ 1.5 kgf.m, 7.2 ~ 10.8 lb-ft) ...
Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between terminal “1” and “2”.
2.
Inspect the voltage value whether it is the regular value or not. ...
Other information:
Removal
In case of replacing the controller (ECU) and transfer case
due to changing characteristics of the frictional materials inside the
transfer case, it is necessary to check and enter the calibration data.
