Inspection

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 = 0.00878835 * Pressure + 0.37081095 [PSIA]

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. | Disconnect the A/C pressure transducer connector (3P) (A).

4. | Remove the A/C pressure transducer (B).

Tightening torque:
10~12 N.m (1.0~1.2 kgf.m, 7.4~8.8 lb-ft)

Take care that liquid & suction pipe are not bent.

5. | Installation is the reverse order of removal.
