      *a

      Component without harness connected

      (Air Conditioning Pressure Sensor)

      Connect the positive (+) lead of a DC 5 V power source to terminal 3 and the negative (-) lead to terminal 1.

    4. Connect the positive (+) lead of the voltmeter to terminal 2 and the negative (-) lead to terminal 1.

    5. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection

      Condition

      Specified Condition

      2 (PR) - 1 (-)

      Refrigerant pressure:

      0.39 to 3.187 MPa (57 to 463 psi)

      0.92 to 4.9 V

      If the result is not as specified, replace the air conditioning pressure sensor.
