increments.NOTE:
- Rotate the joint area smoothly using only the tips of your fingers.
- The electric variable valve timing motor joint moves in 15° increments, and if the joint is moved 24 times, it rotates one full rotation.
- If it does not rotate smoothly, replace the electric variable valve timing motor/driver. (Refer to ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION .)
- Install in the reverse order of removal.
