    Hi All.
    Hoping to get some info on here before hearing what the mechanic says about this.
    I have ~180k miles on this truck, never had any major problems, very reliable.
    Check engine light came on yesterday so I brought it to my local place that does my oil change which is not a dealership. Told me the two codes were P0418 and P2441 - secondary air injection system control and secondary air injection system switching valve stuck bank 1. Told me the truck was basically shot. I drove it over to the dealership nearby and left it there for them to take a look and see what they say. Won't have an answer most likely for a few days as it's Friday afternoon right now…What do you think?
    Any suggestions welcome.

    This other shop said your truck is "shot"????

    Lol your truck is far from shot.... it probably needs the tsb done. The air injection system can get water or moisture in it. The pump flows the air and moisture into the valves, then the truck sits and the moisture rusts the valve stuck. There are all updated parts to put in. Also have u had the recall reflash done for that problem? Have u been to the dealer in the last 2 or so years? They reflashed the ecu to make the pumps turn on everytime u shit the truck off. This clears the lines of moisture...

    "Shit the truck off" heh heh. Hey Jace, Do I need the flash? My pumps do not turn on when I sh*t the engine off. I'm not having any issues, but I wasn't aware of a TSB for that.

    Thanks for the input! I'm waiting to see what they tell me from the dealership, and I'm pretty sure that I haven't taken it to my local one in over two years. I read that other people have had a similar issue fixed under an extended warranty by toyota, supposedly the air injection system had a known issue within the 2nd gen tundras so they extended the warranty from 5 years 60k miles to 10 years 150k miles. Which of course I'm past the 150k mile mark so we'll see…also, what is "tsb"? I just got a recall notice about a wiring issue that can start a fire so I had planned on bringing it in anyway. Hoping for the best!

    TSB- Technical Service Bulletin, I have an 08 and went through this very same problem @ 60k miles. They did the flash and it did not fix it. Had to bring it back, and that's when they said it was the air injection pump. Good luck with that, I hope they can cover it for you, because it's a costly fix.

    If it's not covered under warranty and the repair cost is high, do a search for the air injection pump bypass kit. Hewitt or Hewitt Industries makes and sells them if I remember correctly. The bypass kit may help with your problem.

    The dealer by me just fixed my P0418 issue under warranty for my 2010 5.7 DC. But It only had 12k miles on it when I brought it into them. My general feeling was that they made an exception based on mileage, but I could be wrong. Also, and I'm not sure if this is true or not, but I was also told that my truck was originally designated for sale on the west coast, and that may have helped with warranty coverage as well.
    I wasn't looking a gift horse in the mouth so I just nodded and said ok when they said it was on the house.

    AIP free fix is now 10yrs/150K miles, at least for my 07.

    ...well there you have it then.

    My guess is that even if you are outside the mileage but well within the time-span, if you throw the adult version of a temper tantrum (politely escalating the issue from supervisor to supervisor, to writing letters etc), you might be able to get it covered. That has worked for me in the past.

    I had this happen on my 06 Tundra at around 170k . I researched it quite a bit and since I was past my warranty period I found that my only two options were to replace it with expensive Toyota parts or have this mod done (ask someone with more knowledge like LOTSOFTOYS if this is a good idea or not, but it seems legit. (I would try the reflash mentioned above first though)

    Here is a link from when I was looking into it a while back.

    http://www.tundraheadquarters.com/blog/air-injection-system-bypass-module/

    I ended up ignoring it instead of trying the module and the engine code went away after a while. (This is due to the fact that with cold weather the pump can easily get stuck open or closed. Never had a problem again until the following winter the first time it got real cold, and at that point I decided to fix the truck up a bit and sell it for a new one).

    It is also worth mentioning that the module doesn't actually fix anything, it just tricks your truck into thinking that everything is okay. Which is actually fine, because if I remember correctly, the secondary air injection system only comes on to reduce emissions during a cold start. So in short, It won't hurt anything if this system isn't functioning (which is why I chose to ignore it), but you should definitely have it fixed in some way so the engine code goes away and you don't miss problems that may arise in the future.
