Measure the pressure of high pressure line by measuring voltage output between terminals No. 1 and No. 2.
2.
Inspect the voltage value whether it is within the specified range.
Voltage = 0.00878835 * Pressure + 0.5[PSIA]
3.
If the measured voltage value is not within the specification, replace the A/C pressure transducer.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/charging station.
•
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work.
3.
Disconnect the A/C pressure transducer connector (A).
4.
Remove the A/C pressure transducer (B).
