Vacuum Switching Valve

About this product

The Vacuum Switching Valve (#9091012014) (VSV), a crucial component in Toyota's Engine-Fuel/Vacuum Piping system, primarily serves to control the flow of vacuum to the Vacuum Operated EGR Valve. As the engine operates, the VSV switches on and off, regulating the vacuum effect and managing the release of unburnt fuel into the intake manifold through the EGR system. This process helps in reducing emission levels. Being a genuine Toyota part, the VSV aligns perfectly with your vehicle, and is further protected by Toyota's genuine parts warranty. Over time, the VSV can become clogged or damaged, causing the engine to run inefficiently, increase fuel consumption, and possibly allow harmful emissions. Hence, regular replacement is highly recommended. By ensuring optimum fuel combustion and emission control, the VSV greatly contributes to the overall efficiency and safety of your Toyota vehicle.
