      (to Diesel Turbo Pressure Sensor)

      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 Condition Specified Condition
        3 (VC) - 1 (E2) Ignition Switch ON 4.5 to 5.5 V

      3. Turn the ignition switch off.

      4. Reconnect the sensor connector.

    2. Check the vacuum and pressure.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the intelligent tester on.

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

      5. Disconnect the vacuum hose from the sensor.

        Using SST, apply pressure to the sensor.

        SST
        09992-00242

      7. Using a vacuum pump, apply vacuum to the sensor.

      8. 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 specified, replace the diesel turbo pressure sensor.
