Third generation YP (2014-2021) / Kia Sedona YP Service Manual / Heating,Ventilation And Air Conditioning / Air conditioning System / A/C Pressure Transducer Repair procedures

Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between terminals “1” and “2”.

2.
Inspect the voltage value to determine whether it is within specification.

3.
If the measured voltage value is not wihtin specification, replace the A/C pressure transducer.

Voltage = 0.00878835 * Pressure + 0.5

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 (B).

Tightening torque :
10 ~ 12 N.m (1.02 ~ 1.22 kgf.m, 7.4 ~ 8.8 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).
