Checking the electric valve timing motor
Attention.
- A hot engine can cause burns. Before starting work, turn off the engine and wait until it cools down.
- Do not disassemble the electric valve timing actuator as it is a precision unit.
- Do not apply excessive force to turn the valve timing actuator connection. If you turn it with excessive force, the actuator may be damaged.
1. Disconnect the negative battery terminal.
2. Remove the decorative engine cover.
3. Remove the electric drive of the valve timing regulator.
4. Rotate the phase regulator electric drive connection left and right with your fingers to ensure that it rotates smoothly in 15° increments.
Note:
- Gently rotate the connecting area with your fingertips.
- The phase regulator electric drive rotates in 15° increments, which means that if you move the rotor 24 times, it will rotate one full revolution.
5. If the rotor does not rotate smoothly, replace the phase regulator electric drive with a new one.
6. Installation is carried out in the reverse order of removal.
Checking the electric phase shifter
Attention.
- A hot engine can cause burns. Before starting work, turn off the engine and wait until it cools down.
- Do not disassemble the electric phase shifter as it is a precision unit.
1. Disconnect the negative battery terminal.
2. Remove the decorative engine cover.
3. Remove the electric valve timing motor.
4. Rotate the eccentric shaft of the electric phase shifter by hand to ensure smooth rotation. If jamming is felt, replace the electric phase shifter with a new one.
Note:
- To facilitate turning the eccentric shaft, hook your finger into the connecting groove.
- The eccentric shaft stops rotating when it reaches the maximum lag position when rotating counterclockwise (if you look from the front), and also when reaching the position of maximum advance when rotating clockwise.
- The eccentric shaft rotates 15.8 revolutions from the maximum retardation position to the maximum advance position.
5. Installation is carried out in the reverse order of removal.
