Goss Solenoids Engine vacuum and the solenoids that control vacuum pressure play a large part in the function of various systems on modern vehicles. These can range from emission systems, Exhaust gas recirculation systems (EGR), Variable Geometry Turbochargers through to 4WD engage / disengage systems. As you can see these are all vital components to maximising the performance and handling of your vehicle so when they are faulty or malfunctioning your vehicle suffers. The VSV (Vacuum Solenoid Valve - also known as Boost Control Solenoids, Electro pneumatic Valves, Pressure Transducers or Electric Switch over Valves) are used in many systems on your vehicle and the symptoms indicating a malfunctioning or failed valve can be highly varied: Insufficient power Turbo lag (on turbocharged vehicles) Black smoke Hesitation Vehicle in Limp Home Mode No 4WD activation Constantly monitored by the on board diagnosis system for continuity, short circuit and short circuit to ground, your Vacuum Solenoid Valve can be one of the last points of call for reliably detecting failures and malfunctions are frequently attributed to other components. A frequent cause of a valve malfunctioning is water or dirt ingress through leaky hose joints or broken hose connections. Due to the extreme environments these operate under high ambient temperatures can also cause intermittent malfunctions.
