Refrigerant Pressure Sensor / Switch: Testing and Inspection
A/C PRESSURE TRANSDUCERINSPECTION
1. Measure the pressure of high pressure line by measuring voltage output between NO. 1 and NO. 2 terminals.
2. Inspect the voltage value whether it is sufficient to be regular value or not.
Voltage = 0100878835 * Pressure + 0.5 [kgf/sq.cm]
3. If the measured voltage value is not specification, replace the A/C pressure transducer.
