Checking the electric camshaft adjuster 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 camshaft adjuster actuator as it is a precision unit.
- Do not use excessive force to turn the camshaft actuator connection. If you rotate 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 motor connection left and right with your fingers to make sure it turns smoothly in increments of 15".
Note:
- Gently rotate the connecting area with your fingertips.
- Phase regulator motor rotates in increments of 15", which means that if you move the rotor 24 times, it will turn one full revolution.
5. If the rotor does not rotate smoothly, replace the phase regulator electric drive with a new one.
6. Installation is made in an order, the return to removal.
Checking the electrical 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 camshaft adjuster motor.
4. Turning the eccentric shaft of the electric phase shifter by hand, make sure that the rotation is smooth. If jamming is felt, replace the electric phase shifter with a new one.
Note:
- To facilitate turning the eccentric shaft, hook the connecting groove with your finger.
- The eccentric shaft stops rotating when it reaches the maximum retard position when turning counterclockwise (when viewed from the front), as well as when reaching the maximum advance position when rotating clockwise.
- The eccentric shaft rotates 15.8 revolutions from maximum retard to maximum advance.
5. Installation is made in an order, the return to removal.
