      Check the wire harness.


      1. Disconnect the A23 air conditioner pressure sensor connector.

      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        A23-1 (-) - Body ground Always Below 1 Ω

      3. Turn the ignition switch to ON.

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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        A23-3 (+) - Body ground Ignition switch ON 4.75 to 5.25 V

      (Air Conditioning Amplifier Assembly)

      Check the air conditioner pressure sensor.


      1. Set the manifold gauge.

      2. Connect the connector to the air conditioner pressure sensor.

      3. Warm up the engine.

      4. A/C switch on.

      5. Using a voltmeter, measure the voltage between connector terminals 7 (PRE) and 5 (SG-2) of the air conditioning amplifier assembly.

        Tech Tips

        Check from the rear of the connector while it is connected to the air conditioning amplifier assembly.

        Standard Voltage
        Tester Connection Refrigerant Pressure Specified Condition
        7 (PRE) - 5 (SG-2)

        0.196 to 3.14 MPa

        (2.0 to 32 kgf/cm2, 28 to 455 psi)

        		 0.66 to 4.88 V

      (to Air Conditioner Pressure Sensor)

      Check the wire harness.


      1. Disconnect the connector of the air conditioner pressure sensor.

      2. Using an ohmmeter, measure the resistance of the wire harness side connector.

        Standard Resistance
        Tester Connection Condition Specified Condition
        A23-1 (-) - Body ground Always Below 1 Ω

      3. Turn the ignition switch to ON.

      4. Measure the voltage of the wire harness side connector.

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        A23-3 (+) - Body ground Ignition switch ON 4.75 to 5.25 V
