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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        3 (VC) - 1 (E2) Ignition switch ON 4.75 to 5.25 V

      4. Turn the ignition switch off.

      5. Connect the diesel turbo pressure sensor connector.

      6. Clear the DTCs.

    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 / Atmosphere Pressure and MAP.

      5. Disconnect the vacuum hose from the diesel turbo pressure sensor.

      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
        Pressure applied Indicates pressure
        Vacuum applied Indicates vacuum

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