MANIFOLD ABSOLUTE PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR


    1. Check the power source voltage.


      1. Disconnect the manifold absolute pressure sensor connector.

      2. Turn the power switch on (IG).

        (to Manifold Absolute Pressure Sensor)

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

        Standard Voltage
        Tester Connection Condition Specified Condition
        F12-3 (VC) - F12-2 (E2) Power switch on (IG) 4.75 to 5.25 V
        F12-1 (PIM) - F12-2 (E2) Power switch on (IG) 3.0 to 5.0 V

      4. Connect the manifold absolute pressure sensor connector.

    2. Check the intake manifold pressure.


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Turn the GTS on.

      4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP.

      5. Read the MAP value.

        OK
        Same value as the actual atmospheric pressure

        Tech Tips


        • Standard atmospheric pressure is 101 kPa(abs) [760 mmHg(abs)]. For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure).

        • Also, check "Atmosphere Pressure" in the Data List.
