Toyota 90910-12276 Valve, Duty Vacuum Switching

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.

The EVAP canister purge valve is located behind the air filter housing on four-cylinder models and on the left end of the front bank cylinder head on V6 models.

No, the location of components within the EVAP system can vary depending on the model year and vehicle. Different components might need to be serviced based on the specific model.
