MANIFOLD ABSOLUTE PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK DIESEL TURBO PRESSURE SENSOR


    1. A00YXCNC02
      *a Front view of wire harness connector (to Diesel Turbo Pressure Sensor)

      Inspect the power source voltage.


      1. Disconnect the diesel turbo pressure 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 4.75 to 5.25 V

      3. Turn the ignition switch off.

      4. Reconnect the diesel turbo pressure sensor connector.

    2. Check the vacuum and pressure.


      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.


        Powertrain > Engine > Data List
        Tester Display
        Atmosphere Pressure
        MAP

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

      6. A00YRS2E01

        Using SST, apply pressure to the diesel turbo pressure sensor.

        SST
        09992-00242

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