VARIABLE VALVE TIMING ACTUATOR INSPECTION [ZJ, ZY]

id0110005060b7

  Caution

  • The variable valve timing actuator cannot be disassembled since it is a precision unit.

1. Disconnect the negative battery cable.

2. Remove the ignition coil. (See IGNITION COIL REMOVAL/INSTALLATION [ZJ, ZY].)

3. Disconnect the ventilation hose.

4. Remove the cylinder head cover.

5. Remove the splash shield (RH). (See DRIVE BELT REPLACEMENT [ZJ, ZY].)

6. Verify that the camshaft knock pin hole of the variable valve timing actuator and the T- mark of the cover are aligned and fixed as shown in the figure.

  • If the camshaft knock pin hole and the T-mark of the cover do not align, rotate the crankshaft two times in the direction the engine rotates, and then verify that they are aligned.

  - If it does not align, replace the variable valve timing actuator.

  • If under any condition the variable valve timing actuator makes a hitting noise directly after the camshaft exceeds maximum lift while rotating the crankshaft two times in the direction of engine rotation, replace the variable valve timing actuator as it has not been fixed.

7. Install the splash shield (RH). (See DRIVE BELT REPLACEMENT [ZJ, ZY].)

8. Install the cylinder head cover. (See Cylinder Head Cover Installation Note.)

9. Install the ventilation hose.

10. Install the ignition coil. (See IGNITION COIL REMOVAL/INSTALLATION [ZJ, ZY].)
