Are you not explaining yourself correctly OR maybe your not understanding this system correctly? Download the service manual and check out (in my 2008 manuals) Volume 2, section/page 9-387 Titled 'Secondary Air Injection System'. This pump is a PUMP, it does not induce a vacuum. it pumps ambient air into the exhaust manifolds and is related to emissions. Good luck!
