    Default air induction valve

    I was told that I need a new air induction valve, (check engine light was on). It is on order, but will not be released until May 9th, so I'm out of a truck for 2 weeks. This past weekend, I was hauling a boat, and was only able to go 50 mph. Does anyone have a suggestion on finding this part any sooner than May 9th? I have an 07 Crewmax w/ 5.7 liter. Thanks in advance for any suggestions, redbelly

    Probably not much you can do about getting the part. You could disconnect your AIP pumps and drive without them until the part gets here. That would keep your truck out of limp mode.

    The theory is that if you disconnect the pumps you will get the CEL for the pumps but it will not put the truck in limp mode because it never runs the rest of the tests. I guess nobody knows whether that is 100% successful for all the possible error conditions.
    Bill3508 is probably the one to ask about that.

    In my case if I cleared the code it would run fine for about a week. No need to disconnect the pumps. If redbelly is going to have the system repaired then this should work until the parts arrive. If he wants to disconnect the system and leave it as is then he probably needs to clear the code(s) first.

    Do we really need a new Thread on this topic?? Detailed information is posted in the original topic with photos, diagrams, and DIY instructions. A simple search would lead you to:

    If the valves are stuck open then disconnecting the pumps does nothing. Cycle the truck on and off to try to get the valves to close, then disconnect the pumps, if your not in limp after that then the valves have closed and your good to go.

    AIP Solution: Disconnect both air pumps. You will get a CEL ( Codes P0418,P0419)but no limp mode and no affect on performance. AIP system will be shut down preventing valves from opening. There are two pump connectors, one behind the coolant reservoir on the front of the engine and one below the air box along the wheel well. Both are large gray connectors. Disconnect them, tape them up, zip tie them to keep them from getting into anything hot or moving and your done. If you need service done, reconnect them before you take the truck to the dealer. Enjoy.

    The condition only worsen once it starts, until one day the valves will stick open for good, leaving you with no other option than the repair.

    i am going through the same problem. i have an 08 with the 4.7l v8 that has 86k miles on it. i was quoted $2500 by my local dealer to fix this.

    i saw the pics posted by kfxbryan of his pumps and when i took my fender well apart, there is only one pump. all the posts i have read say there are 2 pumps on the 4.7l but i cannot find another. i did find that the pump barely had any suction so i took it apart and cleaned it and dried it. it now sounds like a small shop vac.

    the problem now is that the diverter valve must be stuck open. with it stuck open, i cant get my truck out of limp mode. the codes i get are P0419 & P2442. it sounds like i have an exhaust leak on the passenger side. is it possible to clean the valves and get them to work again or do they need to be replaced? and if they need replacement, is it a difficult process?
