    Codes are meaningless without definitions, and those aren't even cpmete codes. What are the letters on front of them? P? C? B? U?

    Yep those are the definitions on the print out. Now does anyone have a suggestion on where I should start with this? Seems like some of these codes are related so possibly fixing one thing will eliminate more than one code. Just a guess though. Obviously I have no experience with this kind of thing. :-)

    Secondary air injection pump pressurized your engine every time you start the vehicle and during it's running. If your start your vehicle and it sounds like loud vacuum cleaner working at the same time for few minutes, it's mean your pump open and pumping air not in engine and you have to reseal your pump, if its sounds like vacuum cleaner running but its not loud for a minute or 2, its mean pump working correctly, but check your hoses if they off or broken, if you do not hear any noise you need to check your fuses, check if any voltage going to pump too, otherwise you will need to replace pump. Thread was here on forum not to long ago about same symptoms when air pump went out and guy had all o2 sensors codes
