Hyundai Genesis: Air Conditioning System / A/C Pressure Transducer Repair procedures
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. 
Voltage = 0.00878835 * Pressure + 0.37081095
|
|
3. |
If the measured voltage value is not within the specification, replace the A/C pressure transducer. |
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. |
Install in the reverse order of removal.
When installing, replace it with a new O-ring (A).
