DTC P0106 Manifold Absolute Pressure Circuit Problem


DESCRIPTION

Refer to DTC P0107 (LandCruiser RM00000187U0CFX_01.html).

P0106
DTC Detection Drive Pattern
DTC Detection Condition
Trouble Area
After warming up engine, idle engine for 10 seconds or more, and then drive vehicle under load (accelerator opening amount 15% or more) for 10 seconds
Either condition is met (2 trip detection logic):
(a) The manifold absolute pressure output is 2.5 V or higher for 10 seconds when idling the engine after warming it up.
(b) The manifold absolute pressure sensor output is 0.25 V or less for 10 seconds when the accelerator opening amount is 15% or more.
  1. Vacuum hose connection
  2. Manifold absolute pressure sensor

HINT:
  1. If DTC P0106 is stored, the following symptoms may appear:
    1. Misfire
    2. Combustion noise
    3. Black smoke
    4. White smoke
    5. Lack of power

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the GTS. 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.
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0106)

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

  1. Read the DTCs.

2.CHECK VACUUM HOSE CONNECTIONS

  1. Check the vacuum hose connections.

    OK:
    Vacuum hose is connected correctly and is not damaged.

Go to step 4
OK


3.REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR

  1. Replace the manifold absolute pressure sensor (LandCruiser RM0000045B300KX.html).

5.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

  1. Connect the GTS to the DLC3.

  1. Clear the DTCs (LandCruiser RM000000PDK1E5X.html).

  1. Turn the engine switch off for 30 seconds or more.

  1. Start the engine.

  1. 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) for 10 seconds or more.

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

    HINT:
    Perform the following procedure using the GTS 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.
