  Caution
  • Variable valve timing actuator can not be disassembled it is a precision unit.

1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

3. Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [L8, LF].)

4. Disconnect the ventilation hose. (See QUICK RELEASE CONNECTOR (EMISSION SYSTEM) REMOVAL/INSTALLATION [L8, LF].)

5. Remove the front suspension tower bar (joint). (See FRONT SUSPENSION TOWER BAR REMOVAL/INSTALLATION.)

6. Remove the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [L8, LF].)

7. Disconnect the oil control valve (OCV) connector.

8. Disconnect the P/S pressure switch connector.

9. Remove the ignition coils. (See IGNITION COIL REMOVAL/INSTALLATION [L8, LF].)

10. Remove the cylinder head cover. (See TIMING CHAIN REMOVAL/INSTALLATION [L8, LF].)

11. Confirm that notch of the rotor and bump of the cover at the variable valve timing actuator are aligned and fitted.

  • If the notch and the bump are not aligned, turn the crankshaft clockwise two rotations. Verify that the bump and the notch are aligned.

  • If the bump and notch are still not aligned, replace the variable valve timing actuator.

  • If, when turning the crankshaft, there is a hitting noise from the variable valve timing actuator each time the cam passes the fully lifted position, it means that the actuator is not secured. Replace the actuator.
