DESCRIPTION

УКАЗАНИЕ:
If DTC P0011 or P0012 is present, check the VVT (Variable Valve Timing) system.
The VVT system includes the ECM, oil control valve and VVT controller. The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure applied to the VVT controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the camshaft timing oil control valve assembly, based on the signals transmitted by several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the camshaft timing oil control valve assembly. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
DTC P0011 or P0012 may be set when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain set even if the system returns to normal after a short time. Foreign objects are filtered out by the oil filter.
УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011 OR P0012)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG).

  1. Turn the tester on.

  1. Select the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    Result:

    Result
    		Proceed to
    DTC P0011 and/or P0012 are output
    		A
    DTC P0011 or P0012 and other DTCs are output
    		B
    УКАЗАНИЕ:
    If any DTCs other than P0011 or P0012 are output, troubleshoot those DTCs first.

  1. Remove the camshaft timing oil control valve assembly.

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

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C (68°F)
    		6.9 to 7.9 Ω

  1. Apply positive battery voltage to terminal 1 and negative battery voltage to terminal 2. Check the valve operation.

    OK:
    Valve moves quickly.

  1. Reinstall the oil control valve.

3.INSPECT OIL CONTROL VALVE FILTER


    COROLLA, AURIS. ZZE150 ZRE151,152 NDE150

  1. Remove the oil control valve filter.

  1. Check that the filter is not clogged.

    OK:
    Filter is not clogged.

  1. Reinstall the oil control valve filter.



NG
CLEAN OIL CONTROL VALVE FILTER
OK


4.INSPECT CAMSHAFT TIMING GEAR ASSEMBLY

  1. Inspect the camshaft timing gear assembly (See page Нажмите здесь).



NG
REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (Нажмите здесь)
OK


5.ADJUST VALVE TIMING
УКАЗАНИЕ:
There are no marks on the cylinder head to match-up for the purpose of checking valve timing. Valve timing can only be inspected by lining up the colored plates on the timing chain with the marks on the pulleys. It may be necessary to remove and re-install the chain to match-up the timing marks (See page Нажмите здесь).

6.CHECK WHETHER DTC OUTPUT RECURS (DTC P0011 OR P0012)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG).

  1. Turn the tester on.

  1. Clear the DTCs (See page Нажмите здесь).

  1. Start the engine and warm it up.

  1. Switch the ECM from normal mode to check mode using the tester.

  1. Allow the engine to idle for 5 minutes or more.

  1. Select the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    Result:
    Result
    		Proceed to
    DTC is not output
    		A
    DTC P0011 is output
    		B
    УКАЗАНИЕ:
    DTC P0011 or P0012 is output when foreign objects in engine oil are caught in some parts of the system. These codes will stay output for a short time even after the system returns to normal. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
