    A few days ago my 2012 Tundra CrewMax TRD SR5 flashed a check eng. light after cranking the second time that day and went into "limp mode". I followed up with the dealer the next day. Over the phone they told me this problem was covered under a special extended 10yr/150k warranty. I took it in They verified the code my ODB-II found which was for a Air Injection System failure and called me later with their bad news: according to them the warranty is only up to 2011 model was covered and after that ONLY the 5.7L engines are covered! I have the 4.6L. Of course I was not happy, especially with the $2200 price tag to repair it. I did not allow them to "fix" it b/c my intention was to take it up with Toyota Customer Care the next day even though they still charged me the hundred dollar diagnostic fee.

    When I got home, I thought "what the heck" might as well use my bluetooth ODB-II device and clear the fault. I did and the check light when off but the traction ctrl light did not. I killed the ignition and restarted and this time no warning lights at all. The truck has been running fine for 2 days now and seems to be fine. The ODB showed all systems normal. Apparently there was either a false positive or it was a temporary glitch with one of the valves. Either way, my advice is if you have this error, make sure the dealer checks the fuses to that system, ask them to reset the fault to see if the component really is "bad" before forking out the mucho dinero. Also, Toyota should cover ALL their cars/trucks with this component system that seems to have issues/glitches and not leave one engine model hanging on an island by itself. The TSB fix on the 5.7s is to "flash" or reset the computer fault but they do not address the 4.6s. I did that on mine and it seems to have cured the problem. The moral of the story is invest in your own ODB device and hold the dealer accountable to their diagnosis...the internet is a wonderful thing.

    Thanks for the info and heads up. Seems to be a lot of this type of "glitch" and lights stuff going on. Especially with the older 1st and early 2nd gen trucks. Was on a road trip these past few days with mine and talked to two different older Tundra owners who both said the same thing. That they were getting a barrage of lights and false indication issues.

    What ODB device do you have?

    It's a relatively inexpensive bluetooth ODB-II that uses this app on your smart phone. I just keep it plugged in and I've had to reset the fault code twice since this started. That get's the truck out of limp mode and it runs normally. This system is just an emissions system and runs only for about the first 1-3 min after start up. I apparently have a clogged or corroded valve b/c it only seems to do it when the humidity is high and the engine has cooled over night. Once it runs and warms up, it's fine. However, today a new development, after some back and forth, Toyota has agreed to cover 80% of the cost to repair...basically I pay some labor and taxes. That makes me feel much better about future purchases seeing as I've been exclusive Toyo since 1993 and have purchased 1 Fourunner, 4 Tacomas, 1 Tundra, 2 Solaras, 1 Lexus, and 1 Highlander over those years. I felt like they needed to step up and they did. Best of luck to the rest of you out there on this issue.

    New guy here. Got the p2440. Just had the entire secondary system replaced. NOW after every 4th start up I get a P2447. (2nd fan closed) and it goes into limp mode. Currently back in shop and they cannot find anything wrong. All fans, valves, o2 sensors, pressure switches, every component that operates the system is working fine as it should. Any suggestions? ( 2010 tundra )

    I just got the p2440 code on my 08 Tundra. Just missed the 10 year window by 25 days so dealer wouldnt fix. I called Toyota and asked if they would authorize the dealer to fix it but they said sorry nothing we can do. I am aware of the limp mode but has any one noticed their truck shifting sort of studdering?

    Have you done any updates through Toyota concerning the AIP system?

    If not, you might get lucky with the bypass kits. However, for this to work, I believe you need to have no codes with the AIP.

    You could get the by-pass, it's literally plug and play.

    I will most likely do the bypass but was curious if any one has noticed theier shifting sort of stutter as a result of this code / issue.

    I have this code coming up now. Will Toyota honor the warranty if I wasn’t the original owner? I’d that a warranty on the vehicle itself or only for the original owner?
