        (to Diesel Turbo Pressure Sensor)

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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        3 (VC) - 1 (E2) Engine switch on (IG) 4.75 to 5.25 V

      3. Turn the engine switch off.

      4. Connect the connector to the diesel turbo pressure sensor.

    2. Check the vacuum and pressure.


      1. Connect the GTS to the DLC3.

      2. Turn the engine switch on (IG) and turn the GTS 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 diesel turbo pressure sensor.
