Are there any Lawyers in the forum? Any chance of a law suit forcing Toyota to repair the parts? I took my 4runner I to the dealer while still under the extended Warrenty period. They claimed they had no idea what was causing the lights why must be BS.

I have the same issue that several other 4Runner owners have. I have a 2005 4Runner Limited with the V8. The error is with the emissions system (air pump and air replacement valves) and requires nearly $3000 in parts and labor from the dealer. I have been trying to get help from the corporate office who keeps telling me that the only help would come from a regional manager. The regional manager wanted to know how I got their number. After several "manager level" folks talking about for 2 weeks while my car sat in a garage I am told they will do nothing for me. Nothing at all. I own 3 Toyotas and have helped purchase 2 others for my mother and father in law. Toyota literally doesn't seem to care about enraging a loyal customer. This is not the first major repair I have had to make on this car. Of course everyone was told for years Toyotas run forever without any problems. Yet the 4Runner with the V* cant make it to 100,000 miles...Toyota customer service has been a severe let down to this point. I would be glad to report back if that changes in the future.

Hi, I've been reading a lot on the forum since I bought an 05 4runner a couple of weeks ago but just registered.

Just wanted to share what I found. You may already know but I haven't ran into it this forum yet. I also had p2441, p1442 and p1445 codes when I purchased it and was pretty horrified when I started reading up on it. Luckily I found something the next day, right before ordering parts from the dealer and looking to have someone do the labor for me. An engineer who I believe owns a Tundra or one of the Toyota v8 vehicle made a bypass module and exhaust block off plates related !! I ordered one, installed it and it Worked!! Cleared the codes, been about a week now and all good!!

It was around $155, I just wanted to share as this saved me thousands and could make others here happy too! Here is a link to it.

Air Induction Pump Bypass Module - AIP Valve Bypass

I ordered one through his ebay... I installed it myself. Pretty straight forward but more like a 2.5-3 hour install for me taking my time with the wiring.
Taking off the front wheels to do the exhaust block plates was the way to go. Maybe tundras have more room to do it without going through the fender wells but on the 4runner it was way easier that way. Hopefully it helps others!

Exact same problem just started on my 2005 4R a few days ago. High pitched (vacuum cleaner like) whine near intake manifold for about 30 secs, then shuts off.

Error code P1441.

Dealer wants $2200-$2500 to replace pump/intake gaskets/air tubes/etc.

Looks like I don't have much choice but to get it repaired or use the AIP bypass kit here:

Air Induction Pump Bypass Module - AIP Valve Bypass

Grrrrrrrrrrrrr, 9-years and 105K pretty-much trouble-free miles and now this crap. Read up on all the complaints, called Toyota customer assistanc - no help there other there :

case # 1410171731

So not much else to do but cave in to the dealer price. Not comfortable going to an independent shop for this kind of repair.

Same problem here. 2005 V8 4WD 4Runner. What a load of bull. 3 out of 4 cars I've owned in my life are Toyotas. I think that track record is about to change.

I'm in the same boat with a similar problem. My issue is a pressure sensor on the air switching valve. From what I can tell, the bypass wont fix this issue, so I will have to engineer my own solution for that.

Why they decided to put an electric pump and valve underneath the intake manifold is beyond me. Even with design mistakes like that, I wouldn't be upset if they actually did something about it like they did with the tundra and sequioa.

After hearing about this and other issues with the 4runner (the cracking/leaky V8 headers, and the driveshaft clunk), I regret buying another Toyota. This is my sixth Toyota, and will likely be my last.

So, the question is how much warranty do you get from the dealer if you pay the three grand and get it repaired? Have they improved the parts so there will be no failure in the future? I'd hate to spend that kind of money and have the pump etc go out in 10K miles.

They aren't going to warranty anything parts related. If you have a 4Runner and they were nice enough to fix the problem under warranty, I wouldn't count on them doing it again after you are out of warranty (even with the known issues with the sequoia and tundra). There are people who have been lucky enough to have the dealer cut them a deal or do it under good faith, but that's probably a one in a thousand shot.

Basically, this is one of those systems that should be disabled/bypassed the day your warranty is up (like most other emissions related crap).

It was the previous owner who had the pump replaced along with the three valves. It was done at 143K I think, in 2013. The dealer gave them a 12 month warranty on parts and labor. My dealer tells me that the system was revamped to eliminate water infiltrating the air pump. So, I'm hoping that the truck will be ok. So, there is a way to bypass the pump?

That's good that they offer a warranty on the parts and labor. There is a bypass for the tundra/sequoia/4runner's with the v8, so I don't know if it will work on the 3rd generation.

I have just experienced the dreaded Secondary Air Injection Pump failure at 111,000 miles on my 2006 V8 4Runner. The dealer is quoting $2300 to fix the problem and no help from Toyota Customer Service or Toyota Customer Experience folks.

Case number 1501150333

I will save my receipt and hope Toyota man's up and take responsibility for the V8 4Runner owners. I am posting on social media explaining my experience as hoping to add to the growing pressure.

I know it's an old thread, but I just had this pop up today. Had the P1445, but no associated harsh starts, and the car is running fine. The most troubling thing is the C1201 code that accompanied it. Wondering if anyone has had the same code pop up on theirs as well. It's a 2005 V8 $wd for reference sake.

I am having p 1445 p2441 and p 1442. I have seen forums and issues like this and am getting extrememly depressed. I love this new 4Runner but I can't even begin to state how frustrating this is. I will have a lawyer write a letter to toyota even if it goes no where. This is disperate treatment. The SAME ENGINES with the SAME issues are getting covered under a 150k warranty? BS toyota...no way out of this one. Get everyone and anyone who has had this problem together and and possibly a class action lawsuit?

This is absolutely proposterous.

I need input. Has anyone used the secondary bypass system that others have noted to pass emissions? I can't get my car passed safety and emissions--which means i can't register it. It's a whole chicken before the egg thing.

If the bypass works, is it a short term fix, or do i leave as is for the remaining life of the motor? The preivous owner has had it in this condition for 2 or more years and says it has run fine. Is there really any performance issues? From what i read there is not.

Please let me know on the bypass as I would rather not spend 2-3k to get my car registered--anger doesn't begin to express my feelings. I can buy a new SBC crate for that....WTF!!!!!!!

There a few people selling workarounds. I bought the little block off plates and a "kit" $70 or so included relay and a resister and where to put it. Install took 10 minutes and been fine for 3 years. This is not a big issue just search, read, and fix it guys.

Now if anyone can fix my sunroof for under $1000 I'll be impressed.

***EDIT -- As a noob to the forum i found quite a few old dead threads through the CEL p codes and the key words I had. Thanks for pointing out the other threads. Please look here for a more complete list Secondary Air Injection Pump Failure on V8's! Important!


Again, I have read. I've read about 5 forums worth of data, talked to Toyota. I asked for opinions and examples of what worked. Forgive me, but I've seen literally HUNDREDS of people who had this problem and DID NOT find a workaround....so I'd rather not be one of the "oh I wish I had tried...."

Can you link where you bought your workaround?

As an update, I talked to Toyota and got the same load of BS everyone else got. My case number is 1507071580. The toyota client experience representative was quite helpful. He clearly had 0 ammo on what to say. He mentioned multiple times that it is a completely different car (reffering to the sequoia and tundra's with the same issues under ext. warr.) ...and when i replied but the engine is the same...he agreed...only to 2 mins later say "They are completely different engines." So needless to say I got the address for sending legal correspondence and said I have a group of hundreds with the same issue. I'm going to make a stink anywhere and everywhere I can ...even if it means nothing. This is piss poor relationship managment and as many have said...this is my 3rd toyo product and I would buy more (mentioned this to they guy on the phone)...and his response was that the toyo i bought didn't go to the dealer enough to prove that it was a loyalty issue.....lol. Anyway I thanked him and moved on to the lawyer. Again, things will not nec. change today or tomorrow...but some of the guys/gals who wasted 3k due to piss poor communication and a part that could literally not have been saved with preventative maint. should be reimbursed!


Any and all workarounds for the issue--please LINK the site and give me your experience. Thanks for the reply!
