What is a variable valve timing (VVT) valve?


The VVT ​​solenoid is responsible for fuel economy by regulating the oil supply to the VVT ​​hub.

Keep in mind:

A low oil level can also cause problems with the VVT ​​solenoid and other parts of the timing system. Each vehicle manufacturer has unique codes indicating a problem with the VVT ​​solenoids, so it is important to have a qualified technician diagnose your vehicle.

How it is done:

  • Disconnect the battery, find the solenoid valve for changing the valve timing and remove the mounting bolts.
  • Disconnect the solenoid and remove the solenoid
  • Lubricate the solenoid and apply lithium grease to the seals on the solenoid coil.
  • Insert the solenoid into the space of the mounting surface
  • Insert mounting screws
  • Fasten the engine cover
  • Reconnect the battery

Our recommendations:

When replacing the solenoid, you may feel a slight resistance, but this means that the seals are installed correctly. To overcome resistance, rotate the solenoid slightly back and forth while pushing down until it is flush with the mounting surface.
