This is the exact reason I dumped my 07 Tundra 4.7. I now have an 07 4Runner Sport with a V6 and consider it to be the best vehicle i have ever owned. If I ever have a need for a pick up again I will buy a Ford F-150 ... hands down.

At this point im working with a guy from the 3rd gen section who is a service advisor at a local toyota dealership. I had the same exact "stuck open code" and Limp mode issue on my truck last week as you did, The second that occurred I disconnected the battery and waited about an hour before I reconnected it. After I reconnected it I cleared the codes and it went back to normal. And the Limp mode or any AIP codes for that matter haven't been back. HOWEVER, I still do have that extremely loud noise on cold starts. and its been getting louder.
Of course when I got to the dealer, the truck is hot so they could not replicate the noise. and the only the code they pulled was for a camshaft position sensor. So im fixing that now, and setting up a day asap to leave it over night so they can hear it themselves.
If nothing comes of all of this and toyota doesn't help me out. Then I will obviously be forced to do the repair you made which does look great! and glad to hear its still working as intended.
My question for you is, HOW do I get that kit you got? and how much? I guess you didnt replace the pumps? only did the block off and the relay?

This is borderline crazy, put any other product into the place of your 4runner. Not many companies are going to willingly replace something 4 YEARS outside of the original warranty period.
Listen, most of the times this is an easy fix, and can be done in a few hours with hand tools for NO money 90% of the time.
The inlet pipe for the air pump has a foam filter, which over time with engine heat cycles,starts to deteriorate. When it does it gets sucked into the pump (occasionally damaging some fins in the pump, generally not enough damage to cause the pump to not work), and push the little bits of chopped foam straight into the valves. This causes them to stick.
Snatch off the intake, remove the foam filter, and blow out the pump with compressed air. Remove the valves and use a power probe (or a jumper wire from a 12v source, IE your battery) to actuate the valves and remove any pieces of foam stuck. Then reassemble and you're done. Iv done this to countless tundra's and 4runners and have had VERY few need actual parts replacement, although occasionally it is necessary.
Also, LOL @ responses to get the government involved.
Not to nitpick, but the warranty enhancement isn't because of defective airpumps. Its root cause is water intrusion leading to parts failure.

is it that far out of warranty, or at all?
its considered emissions equipment correct? that carries a different, separate warranty. much longer. right? im positive I read something about that. maybe its in my owners packet.

Happy to report my boy is doing very well. Thanks!
As for the fix:
I got the relay from slyfox75 on this forum. Can't recall but somewhere in the ballpark of $50.
The block off plates came from paul hewitt, here:
Air Induction Pump Bypass Module - AIP Valve Bypass
I think they were around $60.
Paul has a full kit too, but it is much more $$$ than the one SlyFox75 has.
Good luck!

Thanks man! and Glad to hear about the boy! This is a last resort option for me.. However It is an option! I have a badly screwed up a shoulder that takes all the enjoyment out of working on my truck myself and makes it painful. So, either way if it comes down to it, ill probably have someone help me out. but none the less.. Thanks again.
-According to Toyota corp it is out of warranty for even the emissions stuff on This vehicle specifically. Not the Tundra or Sequoia, Anymore. Because they extended it to 150,000 miles on those models for this specific issue.
Even though, 4runners have the exact same issue with the same parts.
*Will update further when I go back to the dealer again.

Have you looked at and read this TSB? It explains how water intrusion is the culprit.
TSB-0329-08
What's interesting is Toyota of Canada released a TSB 11/28/2012 for this problem on the 4Runner. It did not extend the warranty but it outlined the proper diagnosis and repair for this problem.

Please explain how you know it isn't the same issue. And why Toyota would cover the repair cost for some 4runners and not others.

I'll tell you right now not to waste any more energy in trying to Toyota to cover this. They might do a goodwill gesture to where you either pay for parts or labor. The dealer personnel is hand tied when it comes to trying to give an answer on why some models are covered and some not. Have it fixed or do the repair as Dinnertime suggested.
This is not a safety related item. In other words NHTSA is not going to force Toyota into doing a recall. If that was the case Ford would have had to recall a heck of a lot if 4.6 and 5,4 engines for the spark plug issue. You think you have frustration with this? Try simply replacing the plugs on certain model Fords.
I wish you luck and keep us posted.

I agree with you.. and I don't believe toyota Corp will step forward and do anything..but that doesn't mean its right does it? The dealer is the only official avenue you can take to get corporates attention to the issue. So that's what I'm doing.
As far as being a safety issue. That actually can be argued. Do I feel threatened or in danger? No. But when the vehicle sets off the SAI codes it disables all the traction controls. Why? Who knows... Doesn't makes sense to me. But those are there to aid in the the safety of the vehicle so why disable them for an emissions issue?

I dont see anything in here that says ( Except 4runner) is simply just does not state the vehicle. a 2uz-FE is the engine affected with this SAI being the problem that is recognized. Not bringing the warranty over to all vehicles with this engine and that problem is wrong. Especially when they fix some, and not others and for no other reason than publicity.

You're correct that the OP's DTC is not specifically covered under TSB-0160-11, but that does not mean that the OP's symptoms are not related to the issues outlined in the DTC.
If you reference TSB-0230-12, which is an updated TSB designed to provide diagnostic criteria for other vehicles with 2UZ-FE engines (seems to be the VVTi-Equipped units for both TSBs) you'll see that they want to try replacing the Driver for the Air Injection pumps first. Yet towards the end of the TSB they outline diagnostic criteria for failing the Air Injection Pumps and requiring replacement. While this is in no large way an admission of guilt, it does roll into the fact that TSB-0160-11 details how MULTIPLE engine families shared in the Tundra/Sequoia have a potential to accrue too much moisture into the pumps and valve assemblies which can cause problems. The 2UZ-FE in the Tundra/Sequoia is not different than the 4Runner or Landcruiser applications in which the VVTi-equipped units are used. This would infer that the parts are just as susceptible to failure, Toyota even mentions Debris in TSB-0230-12 (which as you pointed out could also be due to deteriorated foam material, I won't discount that at all), debris that could be the result of moisture eroding internal components as seen in the Tundra/Sequoia.
As for warranty coverage, TSB-0160-11 also details that select states (including California) have an extended 84mo/70k emissions warranty covering these components. Additionally TCP-ZTQ-0001-D (Campaign Publication Documentation) supplements the existing TSB with a Warranty Extension pushing that warranty to 10yr/150k from vehicle first use date for these afflicted vehicles as long as the conditions can be replicated and/or have be documented prior to 10yr/150k period.
Documentation for review:
T-SB-0160-11.pdf
T-SB-0230-12.pdf
T-CP-ZTQ-0001-D.pdf
I am only trying to point out that there is plenty of evidence to show that Toyota is aware the issue extended among a large selection of 2UZ-FE Engines, but they have only chosen to specifically cover the Tundra/Sequoia. This is despite having evidence and knowledge that similar failures will occur in the other 2UZ-FE equipped vehicles, they simply have chosen to ignore that and at the very least use TSB-0230-12 to try and mitigate responsibility. This is not the first time Toyota has blown off evidence of a design flaw and/or delayed a TSB to exclude a large number of affected vehicles (see T-SB-0121-12 Its Finally Here! ) There are other examples including the possible cylinderhead gasket issue that seems to be mainly isolated to '05 or older 4Runners (yet, mainly failures are below 100k), of which there seems to be a decent amount of evidence to show there was not only an issue, but that the failed part was silently superseded.
