Kia Optima Hybrid: Air Conditioning System / A/C Pressure Transducer Repair procedures

Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals.

2.
Inspect the voltage value whether it is sufficient to be regular value or not.


Voltage = 0.00878835 * Pressure + 0.5[PSIA]

3.
If the measured voltage value is not specification, replace the A/C pressure transducer.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/charging station.
3.
Disconnect the A/C pressure transducer connector (3P) (A).

Tightening torque :
10~12N.m (1.0~1.2kgf.m, 7.4~8.8lbf.ft)

   
Take care that liquid & suction pipe are not bent.
4.
Installation is the reverse order of removal.
