        Specified Condition

        3 (VC) - 1 (E2)

        Ignition Switch ON

        4.75 to 5.25 V

      4. Turn the ignition switch off.

      5. Reconnect the diesel turbo pressure sensor connector.

    2. Inspect the diesel turbo pressure sensor.

      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the GTS on.

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

      7. Using a vacuum pump, apply vacuum to the diesel turbo pressure sensor.

      8. Read the value.

        OK

        Condition

        Map Value

        No pressure applied

        Same as atmospheric pressure

        Vacuum applied

        Indicate vacuum

        Pressure applied

        Indicate pressure

        If the result is not as specified, replace the diesel turbo pressure sensor connector.
