Inspection

  1. Measure the high-pressure line pressure by measuring the output voltage between terminals No. 1 and No. 2.
  2. Check whether the voltage value is within the normal value or not.

    Voltage = 0.00878835 * Pressure + 0.5 [PSIA]

  3. If the measured voltage value does not meet the specification, replace the A/C pressure sensor.

Replacement

  1. Disconnect the negative (-) battery terminal.
  2. Recover the refrigerant using a recovery/recharging station.
  3. Disconnect the dual pressure switch connector (3P) (A).

    Tightening torque: 10 ~ 12 N·m
    Make sure the liquid line and suction line are not bent.
  4. Install in the reverse order of removal.
