  1. Inspect the power source voltage.

    1. Disconnect the sensor connector.

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

      Standard Voltage:
      Tester Connection
      		Switch Condition
      		Specified Condition
      C80-3 (VC) - C80-1 (E2)
      		Engine switch on (IG)
      		4.5 to 5.5 V

    3. Turn the engine switch off.

    4. Connect the sensor connector.

  1. Check the vacuum and pressure.

    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the intelligent tester on.

    3. Enter the following menus: Powertrain / Engine / Data List / Map and Atmosphere Pressure.

    4. Read the value.

      OK:
      Condition
      		Map and Atmosphere Pressure Value
      No pressure applied
      		Same as atmospheric pressure
      Vacuum applied
      		Becomes vacuum
      Pressure applied
      		Becomes pressurized
      If the result is not as specified, replace the sensor.
