Electric Variable Valve Timing Motor/Driver Inspection

CAUTION:
  • Do not disassemble the electric variable valve timing motor/driver because it is a precision unit.
  • Do not apply excessive force when rotating the electric variable valve timing motor joint. If it is rotated with excessive force, the electric variable valve timing motor could be damaged.
  1. Rotate the electric variable valve timing motor joint to the left and right by your fingers and verify that it rotates smoothly in 15°  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.
