What is the purpose and operation of the Active Control Engine Mount and Diverter Valve?

The Active Control Engine Mount is a component that generates vibrations to cancel out engine vibration and reduce noise at idle. It operates using a Diverter Valve that utilizes engine vacuum to vibrate a diaphragm within the mount. This vibration is then transferred to a liquid inside the mount, which in turn transfers the vibration to the mount's rubber pad, effectively canceling out the engine vibration. To replace the VSV, the two vacuum hoses and the large hose connected to it must be disconnected and labeled for proper reassembly. The valve's mounting bolt and electrical connector are then removed, followed by the disconnection of the remaining hose. The installation process is the reverse of the removal steps.
