AIR CONDITIONING PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT AIR CONDITIONING PRESSURE SENSOR


    1. Install a manifold gauge set.

    2. Disconnect the connector from the air conditioning pressure sensor.

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

      A004UBDE01

    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 - 1

      Refrigerant pressure:

      0.39 to 3.187 MPa (57 to 463 psi)

      		 1.0 to 4.9 V

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