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 ...

Evaporator Temperature Sensor Description and Operation
