Kia Niro: 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.

Check if the voltage is within specification.

Voltage = 0.00878835 * Pressure + 0.37081095

3.

If the measured voltage is not wihtin 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 (A).

  

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).
