Hyundai Kona: Air Conditioning System / A/C Pressure Transducer Repair procedures

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 sufficient to be regular value or not.
Voltage = 0.00878835 * Pressure + 0.37081095
3.
If the measured voltage value is not wihtin specification, replace the A/C pressure transducer.
Diagnosis With GDS
1.
The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).
※ The diagnostic system (GDS) provides the following information.
(1) Self diagnosis : Checking the failure code (DTC) and display.
(2) Current data : Checking the system input/output data state.
(3) Actuation test : Checking the system operation condition.
(4) Additional function : Other controlling such as he system option and zero point adjustment.
2.
Select the 'Car model' and the system to be checked in order to check the vehicle with the tester.
3.
Select the 'Current data' menu to search the current state of the input / output data.
The input / output data for the sensors corresponding to the A/C Pressure Transducer can be checked.

Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery / charging station.
3.
Disconnect the A/C pressure transducer connector (A).

4.
Remove the A/C pressure transducer (A).
Tightening torque :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

  
Be careful not to bend the liquid & suction pipe.
5.
To install, reverse the removal procedure.
  
When installing, replace it with a new O-ring.
