  1. Check the wire harness.

    1. Disconnect the connector of the pressure sensor.

    2. Measure the resistance of the wire harness side connector.

      Standard resistance:
      Tester Connection
      		Specified Condition
      1 - Body ground
      		Below 1 Ω

    3. Turn the ignition switch on (IG).

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

      Standard voltage:
      Tester Connection
      		Specified Condition
      1 - 3
      		4.7 to 5.3 V
      1. If the result is not as specified, replace the pressure sensor.

  1. Check the pressure sensor.

    1. Set the manifold gauge.

    2. Connect the connector to the pressure sensor.

    3. Warm up the engine.

    4. Switch the A/C ON.

    5. Measure the voltage.

      Standard voltage:
      Tester Connection
      		Refrigerant Pressure
      		Specified Condition
      for Automatic Air Conditioner:
      E41-9 (PRE) - E41-13 (SG-2)
      		0.176 to 3.025 MPa (1.8 to 30.9 kgf/cm2)
      		0.76 to 4.74 V
      for Manual Air Conditioner:
      E42-12 (PRE) - E42-10 (SG-2)
      		0.176 to 3.025 MPa (1.8 to 30.9 kgf/cm2)
      		0.76 to 4.74 V
      1. If the result is not as specified, replace the pressure sensor.
