Kia Carens: Air conditioning System / A/C Pressure Transducer Repair procedures
| 1. |
Measure the pressure of high pressure line by measuring voltage output
between terminal “1” and “2”.

|
| 2. |
Inspect the voltage value whether it is sufficient to be regular value
or not.

|
| 3. |
If the measured voltage value is not wihtin specification, replace the
A/C pressure transducer.
|
Voltage = 0.00878835 * Pressure + 0.4
|
|
| 1. |
Disconnect the negative (-) battery terminal.
|
| 2. |
Recover the refrigerant with a recovery/charging station.
|
| 3. |
Disconnect the A/C pressure transducer connector (A).
|
| 4. |
Remove the A/C pressure transducer (B).
|
Tightening torque :
10 ~ 12 N.m (1.02 ~ 1.22 kgf.m, 7.4 ~ 8.8 lb-ft)
|

|
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).
