Warning

•  A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.

Caution

•  Do not disassemble the electric variable valve timing actuator because it is a precision unit.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

3.  Remove the electric variable valve timing motor/driver. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

4.  Rotate the eccentric shaft of the electric variable valve timing actuator by hand and verify that it rotates smoothly.

•  If it does not rotate smoothly, replace the electric variable valve timing actuator. (See ELECTRIC VARIABLE VALVE TIMING ACTUATOR, HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

•  If there is no malfunction, go to the next step.

Note

•  Hook a finger onto the joint groove of the eccentric shaft to rotate the shaft easily.

•  The eccentric shaft stops rotating at the maximum retard position when it is rotated counterclockwise as viewed from the front, and at the maximum advance position when rotated clockwise.

•  The eccentric shaft rotates 15.8 turns from the maximum retard position to the maximum advance position.

5.  Install in the reverse order of removal.
