Kia Rio: Air Conditioning System / A/C Pressure Transducer

Kia Rio 2017-2025 YB Service Manual / Heating,Ventilation, Air Conditioning / Air Conditioning System / A/C Pressure Transducer

Description and operation
Description

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
Inspection
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.

Replacement
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
