Kia Soul EV (PS EV) 2015-2020 Service Manual / Heating,Ventilation, 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 No. 1 and No. 2.

2.
Inspect the voltage value whether it is within the specified range.


Voltage = 0.00878835 * Pressure + 0.5[PSIA]

3.
If the measured voltage value is not within the specification, replace the A/C pressure transducer.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/charging station.
   
If PAG oil mixes into the POE oil of the system, dielectric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.
3.
Disconnect the A/C pressure transducer connector (A).
4.
Remove the A/C pressure transducer (B).
[Without Heat Pump]

[With Heat Pump]

   
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).

    A/C Pressure Transducer Description and Operation
    Description The A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. Engine ECU converts the voltage value to control the cooli ...
