INSPECTION PROCEDURE


HINT:

Abnormal Bank
Timing over-advanced
(Valve Timing is Out of Specified Range)
Timing over-retarded
(Valve Timing is Out of Specified Range)
Bank 1
P0011
P0012
Bank 2
P0021
P0022
  1. DTC P0011, P0012, P0021 or P0022 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. Foreign objects are filtered out by the oil filter.
  2. If DTC P0011 or P0012 is output, check the right bank VVT system for the intake camshaft circuit (bank 1).
  3. Bank 1 refers to the bank that includes the No. 1 cylinder.
  4. If DTC P0021 or P0022 is output, check the left bank VVT system for the intake camshaft circuit (bank 2).
  5. Bank 2 refers to the bank that does not include the No. 1 cylinder.
  6. 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, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011, P0012, P0021 OR P0022)

  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.

    		B
    HINT:
    If any DTCs other than P0011, P0012, P0021 or P0022 are output, troubleshoot those DTCs first.

2.PERFORM ACTIVE TEST USING GTS (OPERATE OCV)

  1. Connect the GTS to the DLC3.

  1. Start the engine and turn the GTS on.

  1. Warm up the engine.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (Bank 1) or Control the VVT System (Bank 2).

  1. Check the engine speed while operating the camshaft timing oil control valve assembly using the GTS.

    OK:

    GTS Operation
    		Specified Condition
    OCV OFF
    		Normal engine speed
    OCV ON
    		Engine idles roughly or stalls soon after camshaft timing oil control valve assembly switched from off to on

3.CHECK WHETHER DTC OUTPUT RECURS (DTC P0011, P0012, P0021 OR P0022)

  1. Connect the GTS to the DLC3.

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

  1. Clear the DTCs (LandCruiser RM000000PDK1DIX.html).

  1. Start the engine and warm it up.

  1. Switch the ECM from normal mode to check mode using the GTS (LandCruiser RM000000PDL0Y3X.html).

  1. Drive the vehicle for more than 10 minutes.

  1. Read the DTCs using the GTS.

    HINT:
    DTC P0011, P0012, P0021 or P0022 is output when foreign objects in engine oil are caught in some parts of the system. These codes will stay stored even if the system returns to normal after a short time. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
