ELECTRIC VARIABLE VALVE TIMING ACTUATOR INSPECTION [SKYACTIV-G 2.0]
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 cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
2. Remove the electric variable valve timing motor/driver. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
3. 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].)
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.
4. Install in the reverse order of removal.
