Kia Niro: Air Conditioning System / A/C Pressure Transducer Repair procedures
| 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.
|
| 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).
