The vacuum switching valve (VSV) is a part of the exhaust gas recirculation (EGR) system of the 1998 Toyota Camry. The function of the EGR system is to recirculate exhaust gases to the intake manifold of the engine and thereby reduce the nitrous oxide emissions of the vehicle. 2. What is the purpose of a vacuum switching valve? The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run. 3. What happens when EGR valve goes bad? A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. ... EGR valves can become stuck 'open' or 'closed' due to a build-up of soot particles, carbon deposits and dirt from fuel.
