Vacuum Switching Valve

About this product

The Vacuum Switching Valve (#90910-12059) (VSV) is a crucial component in Toyota's Engine-Fuel Manifold Air Injection and Engine-Fuel Vacuum Piping systems. It primarily controls the flow of vacuum to various parts of the vehicle, regulating functions like fuel emission control and engine idle speed. When operational, VSV uses its intricate valve mechanism to switch the vacuum on and off, thereby ensuring optimal vehicle performance. Poorly functioning or old VSVs however, can lead to improper fuel-air mixtures, impacting engine performance and fuel economy. Therefore, it's important to replace these parts periodically with genuine Toyota parts, which are designed for vehicle compatibility and are backed by Toyota's genuine parts warranty. In the bigger picture, an efficient VSV plays a key role in enhancing the overall performance and safety of your vehicle. It ensures smooth and clean engine operation, contributing to a more environmentally friendly and efficient drive.
