P0106
DTC Detection Drive Pattern DTC Detection Condition Trouble Area
After warming up engine, idle engine for 10 seconds or more, then drive vehicle under load (accelerator opening angle 15% or more) with engine speed at 6000 rpm or less for 10 seconds

When either of the following conditions is met (2 trip detection logic):

(a) The manifold absolute pressure output is 1.8 V or more for 10 seconds when idling the engine after warming it up.

(b) The manifold absolute pressure sensor output is 0.4 V or less for 10 seconds when the accelerator opening angle is 15% or more and the engine speed is 6000 rpm or less.


  • Open or short in manifold absolute pressure sensor circuit

  • Manifold absolute pressure sensor

  • ECM

Tech Tips


  • If DTC P0106 is stored, the following symptoms may appear:


    • Misfire

    • Combustion noise

    • Black smoke

    • White smoke

    • Lack of power

INSPECTION PROCEDURE

Tech Tips


  • If DTCs P0107 and P0108 are output simultaneously, the manifold absolute pressure sensor circuit may have an open or short. Perform troubleshooting for these DTCs first.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0106)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / DTC.

    4. Read the DTCs.

      Result
      Result Proceed to
      P0106 is output A
      P0106 and other DTCs are output B

    A
  2. CHECK VACUUM HOSE CONNECTIONS


    1. Check the vacuum hose connections.

      OK
      Vacuum hose is connected correctly and is not damaged.

    NG
    OK
  3. REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR


    1. Replace the manifold absolute pressure sensor Click here.

  5. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the intelligent tester to the DLC3.

    2. Clear the DTCs Click here.

    3. Turn the ignition switch off for 30 seconds or more.

    4. Start the engine.

    5. After warming up the engine, idle the engine for 10 seconds or more, and then drive the vehicle under load (accelerator opening angle 15% or more) with the engine speed at 6000 rpm or less for 10 seconds or more.

    6. Confirm that the pending DTC is not output again.

      Tech Tips

      Perform the following procedure using the tester to determine whether or not the DTC judgment has been carried out.


      1. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

      2. Input DTC P0106.

      3. Check that STATUS is NORMAL. If STATUS is INCOMPLETE or N/A, drive the vehicle for 5 minutes, idle the engine for 5 minutes, and then check "All Readiness" again.
