    Hey Folks,

    So I bought a high mileage Tundra with 323k miles on it. It is a 2005 Tundra Double Cab 4x4. I am trying to troubleshoot the following MIL/CEL

    P0418 - Air Injection System Air Pump Malfunction
    P2445 - Secondary Air Injection System Pump Stuck On Bank 1

    The car is going into limp mode due to this fault. And I am having to clear the code on a constant basis to drive it. Once I clear the code it drives fine. It does have a high hiss as if a jet engine is running which really never goes away.

    I believe these codes are interrelated. Reading the interweb I was not so sure how to get this fixed. I can take the manifold out and replace the motor if needed. But again is it as simple a Air injection motor swap or something more involved?

    Additionally if its just a motor swap. Does getting a non OEM motor be okay? I see it for $60 bucks online. The OEM is for $450 or something....This is a 3dary vehicle for me so trying my had at a $60 part isnt too bad for me. LMK.

    Thanks

    Several of us around here have bypassed the system instead. Another option for you.

    So I understand we can do a bypass. Would the bypass work for emissions as well. I live in a emissions state so that is my hesitation on this.


    Also I do want to know all the options. Would swapping out the motor work to clear those codes? Cause I need to do some cleaning so taking out the manifold to clean is something I need to do anyway. If I can at the same time go in and just swap the motor out I would consider that.

    You'll need to replace the pump, and the sensor. The price just for the parts is insane!

    I've never heard of anybody failing emissions after installing the bypass kit

    I get u need to replace the pump. What sensor are you talking about? I thought there is a pump and diverter and check valve in the back.
    I am not sure what sensor you are talking about. Can you please help if I am missing anything else.

    Btw I am planning to replace the pump and clean the debris from the diverter. Hope that should be enough.

    And finally I want to do the AIP bypass the pump altogether. I hope this should be enough and cause me to pass emissions as well. https://drive.google.com/file/d/0By7JoJzynrbSSktEc1hxNHdJcTQ/view

    These guys seem to have a pretty well-sorted set of solutions and good customer service. Give them a call, I'm 90%+ sure this will pass emissions. This is the route I would take if I had your codes: https://hewitt-tech.com/store/index.php?l=product_detail&p=12

    Mine hasn't failed and I dont have any codes, so I'm preemptively bypassing the system with one of these BEFORE I develop issues: https://www.ebay.com/itm/Slyfox75-A...G-CABLE-for-Tundra-Sequoia-LC-LX/143371402266

    Sorry, meant the check valves. Why replace anything if you are doing the bypass?
