hi inspect the valve under the hood at the exhaust manifold It will be made of aluminum with a black hose attached to it and aan electrical connector. To test it unhook the hose by squeezing the ends. Once the hose is off start the engine and see if any air comes out of the valve. Nothing should come out not even a little bit. If it does the valve is bad and is dumping condensation from the engine into the air pump which also may need replacement
