MANIFOLD ABSOLUTE PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE

  1. INSPECT NO. 1 TURBO PRESSURE SENSOR

    1. Check the terminal voltage.

      1. Disconnect the No. 1 turbo pressure sensor connector.

      2. Turn the ignition switch to ON.

        (to No. 1 Turbo Pressure Sensor)

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

        Standard Voltage

        Tester Connection

        Condition

        Specified Condition

        B192-3 (VC) - B192-2 (E2)

        Ignition ON

        4.75 to 5.25 V

        B192-1 (PIM) - B192-2 (E2)

        3.0 to 5.25 V

        If the result is not as specified, repair or replace the wire harness or connector.

    2. Check the turbo 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 / Data List / Boost Pressure Sensor.

        Powertrain > Engine > Data List

        Tester Display

        Boost Pressure Sensor

      5. According to the display on the GTS read the Data List.

        OK

        The value is approximately equal to atmospheric pressure.

        Tip:

        • Standard atmospheric pressure is 101 kPa (abs) (758 mmHg (abs)).

        • For every 100 m (328 ft.) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). This varies with the weather.
