Variable Valve Timing Actuator Inspection

VARIABLE VALVE TIMING ACTUATOR INSPECTION [MZR 1.5]

CAUTION:
- The variable valve timing actuator cannot be disassembled since it is a precision unit.

1. Disconnect the negative battery cable.

2. Remove the fresh-air duct and the air cleaner as a single unit. Service and Repair

3. Remove the ignition coils. Service and Repair

4. Disconnect the ventilation hose. Service and Repair

5. Set the vacuum hose out of the way.

6. Remove the cylinder head cover. Service and Repair

7. 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.





8. Install in the reverse order of removal.
