what does an air diverter valve do
The diverter valve switches air flow from the exhaust to the atmosphere when it senses deceleration. The diverter valve uses a manifold vacuum signal to determine deceleration. Most fuel injection systems do not require a diverter valve, since they are able to shut down fuel flow on deceleration.he air management valve or air switching valve, can be used in addition to or in place of a diverter valve. The air management valve is typically used on computerized emission control systems to switch air flow from the exhaust manifold to the catalytic converter or the air cleaner.
