Kia Rio: Air Conditioning System / A/C Pressure Transducer
Description and operation
The A/C Pressure Transducer (APT) convert the pressure value of high pressure
line into voltage value after measure it. By converted voltage value, engine ECU
controls cooling fan by operating it high speed or low speed. Engine ECU stop the
operation of compressor when the temperature of refrigerant line is so high or so
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 to determine whether it is within specification.
Voltage = 0.00878835 * Pressure + 0.37081095
|

|
3. |
If the measured voltage value is not specification, replace the A/C pressure
transducer.
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Recover the refrigerant with a recovery/charging station.
|
3. |
Remove the A/C pressure transducer (A) disconnecting the A/C pressure
transducer connector
