AIR CONDITIONING PRESSURE SENSOR ON-VEHICLE INSPECTION


  1. INSPECT A/C PRESSURE SENSOR


    1. Install the manifold gauge set.

    2. A016045E13

      Disconnect the connector from the A/C pressure sensor.

    3. Connect the three 1.5 V dry cell battery positive (+) lead to terminal 3 and a negative (-) lead to terminal 1.

    4. Connect a voltmeter positive (+) lead to terminal 2 and a 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)

      		 1.0 to 4.8 V

      If the voltage is not as specified, replace the liquid tube sub-assembly (A/C pressure sensor).
