MANIFOLD ABSOLUTE PRESSURE SENSOR ON-VEHICLE INSPECTION


  1. CHECK MANIFOLD ABSOLUTE PRESSURE SENSOR


    1. A01DY0OE01

      Check the power source voltage.


      1. Disconnect the pressure sensor connector.

      2. Turn the ignition switch ON.

      3. Measure the voltage between terminals M3-3 (VC (+)) and M3-1 (E2 (-)).

        Standard voltage
        4.75 to 5.25 V

        If the result is not as specified, inspect the wire harness or ECM Click here.

      4. Turn the ignition switch OFF.

      5. Connect the sensor connector.

    2. Check the power supply.


      1. Turn the ignition switch ON.

      2. Disconnect the vacuum hose from the pressure sensor.

      3. A01E2VTE42

        Connect a voltmeter to terminals E22-2 (PIM (+)) and E22-9 (E2 (-)) of the ECM, and measure the output voltage at ambient atmospheric pressure.

      4. A01DZTGE01

        Apply a vacuum to the pressure sensor in 13.3 kPa (100 mmHg, 3.94 in.Hg) increments until the pressure reaches 40.0 kPa (300 mmHg, 11.81 in. Hg).

      5. Measure the decrease in voltage for each increment.

        Standard voltage decrease
        Applied Vacuum Specified Condition
        13.3 kPa (100 mmHg, 3.94 in.Hg) 0.3 to 0.5 V
        26.7 kPa (200 mmHg, 7.87 in.Hg) 0.6 to 0.8 V
        40.0 kPa (300 mmHg, 11.81 in.Hg) 0.95 to 1.15 V

        If the result is not as specified, replace the manifold absolute pressure sensor.

      6. A01E2UUE01

        Using SST (turbocharger pressure gauge), apply pressure to the sensor in 19.69 kPa (0.20 kgf/cm2, 2.84 psi) increments until the pressure reaches 98.0 kPa (1.0 kgf/cm2, 14.2 psi).

        SST
        09992-00242
      7. A01E2VTE42

        Measure the increase in voltage for each increment.

        Standard voltage increase
        Applied Pressure Specified Condition

        19.6 kPa (0.20 kgf/cm2, 2.84 psi)

        		 0.4 to 0.7 V

        39.2 kPa (0.40 kgf/cm2, 5.69 psi)

        		 0.9 to 1.2 V

        58.8 kPa (0.60 kgf/cm2, 8.53 psi)

        		 1.5 to 1.8 V

        78.5 kPa (0.80 kgf/cm2, 11.4 psi)

        		 2.0 to 2.3 V

        98.0 kPa (1.00 kgf/cm2, 14.2 psi)

        		 2.5 to 2.8 V

        If the result is not as specified, replace the manifold absolute pressure sensor.

      8. Connect the vacuum hose to the sensor.
