Kia Soul EV: Air Conditioning System / A/C Pressure Transducer Repair procedures

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.

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.

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).

Remove the A/C pressure transducer (B).

[Without Heat Pump]

[With Heat Pump]

•	Be careful not to bend the liquid & suction pipe.

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 ...
