Inspection

  1. Measure the high-pressure line pressure by measuring the output voltage between terminals "1" and "2".
  2. Check the voltage value to determine whether it is within the normal range.

    Voltage = 0.00878835 * Pressure + 0.37081095

  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 air conditioner pressure sensor connector (A).
  4. Remove the A/C pressure sensor (A).

    Tightening torque: 9.8 ~ 11.8 N·m
    Be careful not to bend the liquid line and suction line.
  5. Install in the reverse order of removal.
    When installing, replace it with a new O-ring (A).
