Kia Stinger: Air Conditioning System / A/C Pressure Transducer
Description and operation
A/C pressure transducer measures the pressure in high pressure line and converts
it into voltage. Based on the converted voltage, engine ECU controls cooling fan
by operating it at high or low speed. Engine ECU stops the operation of compressor
when the temperature of refrigerant line is too high or low irregularly to optimize
air conditioning system.

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.

|
3. |
If the measured voltage is not wihtin specification, replace the A/C
pressure transducer.
Voltage = 0.00878835 * Pressure + 0.37081095
|
|
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).
