First when you installed a new one, did you clean it througly and all the ports on the engine before installing the new one with a NEW GASKET? Make sure it is tightened down properly, voltage should be aproximately 5v at the connector.
Try what I describe below.
Reset the trouble codes with the valve disconnected and immediately turn the key. Then connect the valve and turn the key back on.
