Kia Forte: Air Conditioning System / A/C Pressure Transducer
Description and operation
The A/C Pressure Transducer (APT) converts the pressure value of high pressure
line into voltage value after measuring it. By converted voltage value, engine ECU
controls the cooling fan by operating it high speed or low speed. Engine ECU stops
the operation of the compressor when the temperature of refrigerant line is very
high or very low irregularly to optimize air conditioning system.
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.
Voltage = 0.00878835 * Pressure + 0.37081095
|
|
3. |
If the measured voltage value 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.
|
3. |
Disconnect the A/C pressure transducer connector (A).
|
4. |
Remove the A/C pressure transducer (A).
Tightening torque :
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)
|
Be careful not to bend the liquid & suction pipe.
|
|
5. |
To install, reverse the removal procedure.
When installing, replace it with a new O-ring.
