Repair Procedures

Inspection

1. Check the sensor voltage output between No.1 and No.2 terminals.




2. Check that the voltage is within spec.

Voltage = 0.00878835 * Pressure + 0.5 [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 dual pressure switch connector (3P) (A).

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





CAUTION:
Take care that liquid & suction pipe are not bent.

4. Installation is the reverse order of removal.
