I appreciate the not going to be an ass part, by pass kit does not work on flex fuel engines, never been a drop of that mess in mine, but that don't change the ECM programing.Not to be an ass Killer because I can see you dont post much, but if you did a search first you would have gotten some good info. Like the fact that you dont have to spend 4K to fix it, you can buy a bypass kit for a fraction of that cost. I typed in P0418 in the search box and this is the second thread that came up. Same year as yours and Hewitt-Tech is the guy that sells bypass kits.
Currently limp mode (p2445/p0418); can I clear check engine lights & drive it 1000mi? Hey guys - Kinda tough situation I'm in and hoping you all could please give me some guidance. I'm getting the P0418 and P2445 secondary air pump codes on '11 Tundra 5.7L. It's been parked at my parents'...www.tundrasolutions.com
I would love to know more about this because I am pretty sure you are simply misinformed or confused with another solution.My mechanic does not want to do the Hewitt bypass, and honestly while a cheap fix, I've read it can cause "other" codes to be thrown...but I don't know for sure since very few post about it's long term fix.
My AIP went out in my 09 5.7 at around 170k miles, and therefore was not covered by any extended warranty. Hewitt-Tech helped me find the perfect solution, and I've had the bypass for 6-7 years/ over 100k more miles now since the problem began with no more limp mode. Perhaps once a year or so, the "ghost of the AIP" re-emerges in the form of a Check Engine light and the same codes, but NO DRIVEABILITY ISSUES. I simply erase the code, and don't see them again for a very long time. I get a state inspection every year and have no issues passing. I highly recommend the Hewitt-Tech solution.Killer, I've been there, done that-----you have to contact Toyota or a dealership to find out if your 2011 VIN is covered. After being a 20+ year Toyota owner (2nd tundra & 3 more) I got the Toyota shaft treatment on my 2012 Tundra 4.6 with that lovely code at exactly 72k miles, nice big$$$$ repair bill out of pocket on well documented ongoing defect in Tundra production. And once again, 6 months and 3k miles later it's gone out again...secondary air pump P4018... and ...no dealer would go to bat even though every service tech says Toyota knows the problem has not been fixed in post 2010 Tundras, , and after weeks of back and forth with corporate (where they admit the defect continues well past the 2010 models)...I had the joy of paying for the repair a 2nd time.
My mechanic does not want to do the Hewitt bypass, and honestly while a cheap fix, I've read it can cause "other" codes to be thrown...but I don't know for sure since very few post about it's long term fix.
Needless to say, I am not happy with Toyota's stance on this issue, am out more on repeated repairs than I have ever spent on any vehicle that I have owned including my 2002 4runner with 250k + miles.. Until Toyota gets enough complaints filed against the secondary air pump issue for post 2010 models, they will not extend the warranty (those are Toyota's words). So, keep your receipts----maybe someday (when pigs fly) you will get reimbursed for your out of pocket repairs on their defective product.
After my 2nd experience stuck at the bottom of a hill, truck in limp-mode with my wife, and 2nd repair in 6 months, I filed a complaint with the U.S. DOT National Highway Traffic Safety Administration. You can do it too...if nothing else, your complaint will be registered along with many, many others for the same issue. Good luck!
Not that code. The 3 codes I've been seeing are P2441, P2443, P0441. Thanks for following up.Is it the p011b Temperature Correlation code? That is why we initially designed the V5 kits to prevent that on the 08-12 vehicles. If you have a V3 or earlier kit on there the V54H or GenII would fix that.

The reason you don't hear about long term is because they are properly engineered to last at least as long as the vehicle. Nothing is perfect though so if there is a problem we have full tech support and cover them with a limited lifetime replacement warranty.
The main reason you don't hear about long term is just simply that people bypass the system and eventually completely forget about the problem.
The very first units I made are still out there in the wild as 7-8 year old electronics. Those would be what the V36H kits are now and they are practically bullet proof at this point and will likely not be updated again.
The GenII is expected to follow suit as the best solution for all vehicles moving forward and would be the much better solution for both your 4.6l vehicles than our current V54H kits for the 08-12 vehicles.
Give me a call to discuss a GenII. You should probably also find another mechanic so you don't keep waisting your money.
Yeah apparently Spectrum was having nationwide problems yesterday and they are the direct upstream provider for our website's hosting company..the servers just didn't have internet.. so frustrating. Site was back online about 4:30est yesterday. To me it looks more like some sort of cyber attack on the spectrum network or everyone trying to see baby Yoda on Disney+ broke the internet.UPDATE & QUESTION:
Took me a while to find this post.
Hi Paul, it's 2 months later...we replaced the bank 1 valve with an aftermarket one (cheap) back in April, but the problem has returned. My tundra is a 2012 4.6. It is getting the P2440 Bank 1 stuck open code, with check engine and trac off lights / limp mode----75k miles, and Toyota corporate will not help. I may have misunderstood my mechanic previously, as I was the reluctant one to install the bypass. Went down to the mechanic yesterday and tried clearing the code, but the problem persists. This time he suggested the bypass, and here I am.
So, yesterday (12/6) I called Becky at Hewitt Tech and ordered the Gen 1 parts. Your website was down, so we placed the order via phone. She said I would need the "pressure sensor harness" plus the "Gen 1 kit". Last night received an email copy of the invoice, but the pressure sensor harness was not included in the order. I just want to get the right parts. could you review the order before it ships? Do I need to revise the order? Any ideas? I just want the problem fixed...and I hope your bypass kit takes care of the problem---just say no to check engine lights and limp mode!
I did not know these were recurring issues on our Tundra's, but some Google searches for fix vids and it seems that they are.
Anyone know if 2011 with under 100K will still be warranty or am I out almost 4K....
