Can’t believe I found this video. The answer to all my problems
Great! Hope it works out for you!
Terry
Hey I just used this video as a guide for the installation on my 05 Sequoia and I’m truly grateful for this . Just wanted to share a tip that worked for me . In my case I live in IL so the bolts were rusted ( as expected) so PB Blaster is my friend ( spray and let sit for a day ) it does make life easier. Also I found the on the driver side you gain more access if you remove the front tire and lit it up . Good luck to whoever is doing this kit.
Thanks or the feedback!!
Terry
Great video guys! I finally cleared my codes on my 05 Sequoia after buying the Hewitt bypass kit and by following your clear and detailed video. Very grateful for this video as the dash warning lights being on all the time was driving me nuts. Just some feedback for your viewers. I had the p1442 and p1445 codes come up on mine. Because these codes mean that the valves are 'shut', I didn't install the block off plates out of fear of breaking a stud off. Common sense told me that if the valve is shut, that it is already blocked off. Installed the bypass kit, cleared my codes and boom, no more dash lights on. So stoked. Here's the huge bonus for me. I also had my ABS and e brake warning lights lit up on my dash also before installing this bypass kit. I couldn't believe it when those lights went off after installing the kit. So bizarre. Brakes felt totally fine when my dash was lit up like a Christmas tree and I had an appointment the very next day at a brake shop to diagnose why those warning lights were on. I got a 2 for 1 by installing this kit and couldn't be happier. Has saved me a shit tonne of money. Thanks again guys, for the great video and thanks Hewitt Tech for an absolute brilliant product! However, out of habit, I still find myself constantly looking down at my dash, checking for warning lights on, after doing it for so long, lol.
Thanks for the awesome feedback and so glad it worked for you!!! I had an EGR valve light on on an old Mazda B2000 for several years. Then it burnt out 😂. Problem solved. 🤪
Terry
You gentlemen are a Godsend, not as mechanically inclined as either of you. This has helped me immensely with my 2005 Tundra. Thank you and you've got an interested subscriber for all your other great content.
You are very welcome and thanks so much for the kind words. Always glad to help. Thanks for watching!
Terry
This wonderful. I just ordered my bypass kit for my 2006 Tundra, and look forward to the install, thanks to your video. I have cleared the P1442 so many times I could do it in my sleep. Thank you again.
Your welcome. Glad to help out. Its what we hope to do😁.
Terry
You guys are great thanks for the awesome detailed video and all the help!
2006 4.7 V8 here;
I was able to successfully install the kit by myself in a few hours.
The block off plates looked intimidating getting to the bolts, but I have to say I found that to be relatively easy thankfully!
I was able to reach 3 out of 4 bolts from the top with a small ratchet & both short & deep sockets.
Had to hit 1 from underneath on passenger side.
I also have long monkey arms.
Hardest part was feeding the wire into the loom haha which I had to go buy because Hewitt did not include the loom with my kit.
Thanks again!
Glad it worked out for you.
Terry
Just did this install on a 2010 Sequoia. 4.6 V8. The block off plates are on top of the engine which makes it easier,, it runs like a scalded dog now. Thanks for the video!!
Great!
Terry
Thanks for the great video and not skipping any of the 'obvious' steps. My 2009 Tundra threw the P2440 code this morning; I've only had the truck for 3 months, so I was upset to learn this was a common problem and that the Customer Support Program to address this expired in Jan 2019. Worse, I learned that my truck had this problem "corrected" in May 2016, yet here it is again. I'll be doing this for sure. Turning wrenches sure ain't like it used to be.
You are welcome. Hope it helps and you get things worked out. Let us know how it goes for you!!
Terry
This was just what I needed to get my Sequoia back on the road, great video that gave me the confidence to tackle this project myself.
Great and thanks for the feedback. Let us know how it works out. There’s not much we won’t try. Dive in head first and get it done!
Terry
Got this done this morning in about an hour and a half by myself. Passenger side was a little more difficult and I did it from underneath. Driver side was easier and I was able to do it from up above. Be careful not to strip any of the nuts. The multimeter never gave me the same reading that it did on this video, but it did work. Thank you
You are welcome! Glad to help.
Terry
@@ForestToFarm With this system pass the emissions test
With this system in place will it pass the emissions test
I can tell you that coincidently I recently had to do omissions test where I live and that it did passed! Ive also read online anout others passing in California even. Obviously make sure that you’re so check engine light is off. So I can’t tell you for sure that it will, but I’d say your chances are very good.
What do you do if the bolt breaks?
I bought a 2005 sequoia last summer and had the p1442 code. I bought the FIXD obd2 port reader for $20 and am glad I came across this video. I ordered the bypass kit today and can reset the cel with the FIXD app. Now I just need to replace the steering rack.... yeeaahhhh
Great! Thanks for sharing.
Terry
Excellent video, great camera shots. I'm going to order up the kit for my 07 Tundra. The dealer wanted $2,200 to replace...oh noooo thanks!
Great!
Terry
And thank you!
Terry
Great video. I have a 2007 tundra. Secondary air pump went out on it at 170,000 miles. Paid 3100 to get it fixed. Wish I knew about this then.
Thank you. Well if it ever goes out again you will know what to do!! Hate that for you. When its a problem on all the trucks over a period of time that spells defective to me and they should have to fix it as a recall.
Terry
Forest To Farm the crazy thing is. The only reason for is to reduce emissions. There hands are tied by the Emissions inspection office or who ever sets those standards. One of those added parts that was required to reduce crap in the air... but yes, if it happens again this will be my next go to.
And what is really crazy is it only does that reduced emissions until the catalytic converter gets warmed up which is probably less than a minute or two.
Terry
FYI on a 2007 tundra 4.7L, block out plate on passenger side is impossible to get to with metal heater core hoses running in front of it. Work around by following that exhaust hose that you're blocking back up to the side of the engine block. The other end of that metal hose connects to another spot with the exactly the same kind of connection, block it there.
Awesome!! Thanks for the valuable info!!
Terry
This is a good video for 2 sets of eyes to add the blocking plates. One down below to help guide the worker above trying to loosen the blind nuts. If you are working alone, like I was, I found that taking off the wheel, removing the plastic pins holding the top of the rubber flap and dropping it down out of the way, gave me visual access to both nuts to loosen and add the blocking plates. If you need some help with corrosion on the nuts, mix equal parts acetone, and auto trans fluid and apply to the nuts.
Thanks. And thanks for sharing your ideas!
Terry
Brian, your getting grey! No doubt from all that hard work you two are doing! As to your process, the only addition I would have would be to put a dab of sealer on the wire where it passes through the housing to seal the box from dust and moisture.
Hahaha yeah I am! Definitely a good idea! We actually meant to do that, but forgot all about it. Focusing on filming can really distract you lol. Thanks for the reminder 👍
Very helpful video. I just finished install and it worked perfectly. Check engine light is gone!
Great! Saves a pile of cash too!!
Terry
. Question, is this a Gen one or Gen 2 kit ? I just called Hewitt and they recommended that g2 which is actually $400
Thanks guys. Much appreciated video. Had it happen to me after 12 years of owning the truck. Ordered the part and will tackle this right away.
You are welcome. And good luck!
Terry!
I'm glad the bolts on your air pipes came off easy. 3 outa 4 of mine broke right off. Safety wired them together until i can find a better fix. I'm in the south with very little rust. Go figure.
Man. Sorry to hear that. Good luck.
Terry
Great video!! I can't tell you how helpful this is. I really appreciate you guys taking the time to do this. Thanks!!
You are very welcome! Thank you for the. Compliment.
Terry
Doing this over the weekend. Really helpful instructions, guys. thanks for sharing.
No problem. Good luck!!
Terry
I installed the kit on a 05 SR5 Tundra today. So far, no check engine light has come on. Im pleased with the product.
Good news! Thanks for sharing.
Terry
Have you had any CEL ‘s? I was good for a few months but now have a CL for mass airflow sensor.
I haven't had any CEL's s since installation. My truck just hit 305,000 miles and runs great. No problems!
do you remember where the block off plates are located on your 05 toyota tundra
Will it pass California smog inspection after bypassing the code?
On my 05 Tundra I had a stuck bank 1 Sec air inj ck valve code P2440, but I ended up pulling the valve without removing the intake sys. Enough room exists in the back providing you lay a thick foam cushion across your engine and lay on the pad. Also, you'll need a 1/4" swivel head ratchet with tight gearing. I bought the Titan 90 tooth swivel head from O'rielly Auto Parts for $17. This is critical to get the two long 10mm bolts on the valve. You should disconnect the vacuum lines that run to the passenger side solenoids because it makes it easier to get the valve out before you disconnect the vacuum line on the removed valve. I ended up cleaning my valve with brake parts cleaner and removed two small pieces of plastic that prevented the check valve from closing. After testing the vacuum with my MityVac to make sure the valve holds vacuum I reinstalled it and the Shop-Vac sound went away, the engine light has stayed off and no fault codes show on my OBD. I ordered two Dorman check valves to replace at a later date, but its an easy job when you don't have to remove the intake assembly. The Hewitt kit is a great idea, but the gen 2 ($450) is the one to buy if you live in Cal, because it will not be detected on the visual when smog inspection comes up.
Sounds like you may know a thing or three about vehicles 😁. Thanks for adding some value to the conversation!! Thanks for watching!
Terry
Thanks for the thorough video guys... I'm installing on my 2006 Lexus GX470.
You are welcome. Glad we could help!
Terry
Good to see you guys out and about again. I like velcro for adding new wires in computers. Not sure how well velcro does in an engine bay, though.
Yes sir, we have been busy lately. Not sure about the Velcro. Seems like it might pick up a lot of dirt. Its not like it was clean under there, lol
Terry
👍👍this is very good to know. My brother has a 2012 Tundra. Not sure if his has this type of emissions but ill be sure to pass this info on. W.V. state doesn't have as strict of guide lines but who knows that can change in the future. Like you everybody else i like too save money too. Thanks Terry and Brian this was very helpful.
Hey Dean. Your welcome. Yeah the 2012 falls into the possible problem trucks as far as I know. So far it has done fantastic. Glad Brian came across this simple and affordable option.
Terry
Thanks guys. Just did this on my 2006 Tundra today!!
You’re welcome! Hope it does good for you. Thanks for watching!!
Terry
Can You please send me the Link to Buy that kit
I have a 2007 Toyota tundra and what you’re talking about the valve sticking under the intake. Mine is melted right up on top of the motor. I am so confused with this. Mine is a 2007 4.7 motor and looks nothing like what you’re working on, my secondary whatever you call it or mounted on top of the motor right side and left side.
Not sure what to say. Brian traded his off in 2021 for a new F150. 😁 Great truck so far.
Terry
Thank you Brian and Terry I fixed it because of your video 🎉🎉🎉🤙🏽🤙🏽
Awesome! Glad to help.
Terry
Great video even in 2024!!
Thanks! Glad to be of help. Thanks for watching!
Terry
Just finished installing today and reset the check engine light...really hoping for the best.
Awesome! Hope it works out for you. Ours is still working great.
Terry
How's it working?
Soooooo? Lol I just ordered what's your status
Can You please send me the Link to Buy the kit.
I've this problem with my 08 5.7L tundra. I replaced the sai valves the first time and it was good for about a year. Now the SAI pump is failing. It only causes an issue in cold starts, usually I will wait for the CEL to come on , then shut off the truck and clear the code then restart and it's fine. But a pain in the ass and I've considered just getting a bypass kit, rather than fixing it again.
Toyota should be fixing this issue. Hate your having all those problems.
Terry
Great instructional video. The wire loom, what size do you suggest? Thank you.
Hey. Not sure what size it was and he traded the truck. It came with the wire loom in the kit. Thanks for watching!!
Terry
@@ForestToFarm I see. My kit did not come with the plastic wire loom. I am just going to get the 1/4”. Thanks. :)
Good job guys looks like what i would have done also. It is awesome that companies makes stuff like that.
Thanks Steve. Yeah they save us all a lot of money. These big corps just want to bleed you dry. Wish us peasants could all get together and just cut them out of the loop, lol. We do our part to fi it ourselves if at all possible. By the way, gonna be needing that mini soon!
Terry
Great video and every computer needs a re-boot every now and than.
Thanks!
Terry
Got it done with help from this video, thanks guys? Great job!
Awesome! Your welcome. Thanks for the feedback!
Terry
Thanks for the detailed video! I’ll be installing mine this week!
Your welcome. Good luck!!
Terry
Hello. I was wondering if you had a link too the kit you purchased. There are a variety of kits for the 06 double cab Tundra.
The link for the kit is in the description of this video. Thanks for watching!
Terry
Congratulations very informative video definitely saves tons of money. I wanna go ahead and give a try but since i live in California i’m concern about not passing smog check. Have you heard of anyone having this kit and not passing it?
Thank you. We have not heard about problems with smog tests but I would be concerned in California. Maybe you can go to a mechanic and get their opinion? Good luck!
Terry
I am following to see if it worked in California.
Any update
@@coachpete2771 any update
I have a 2006 tundra with 79,000 miles and have had it maybe 6 years and been making that noise on start up sense I bought it, no codes and seems to run fine how you know it’s bad? It makes the same sound but no codes? Thanks for the great video guys.
This truck had the noise long before the codes started showing up. The bypass has worked so far! Thanks for watching!
Terry
Hey guys I have the same problem with my 05 Toyota sequoia 4.7L v8 with a code P2445 I replaced all the air secondary injection pump and air secondary injection check Valve. I'm still having the same problem with the same code P2445. Should I bypass what you guys did???
Honestly we are no experts on the subject. I would hate to misguide you. I would call the Hewitt company and see what they recommend. They seem to be very knowledgeable.
Terry
did u end up clearing it?!? I have the same code on my 05 right now too!
@@austinhatton3254 yes my problem was solved bypassing it P2445 now its gone
@@djlouis2150 perfect just got it installed today p2445 cleared and is gone at least so far but idk how to clear this code p1613?!? any ideas on what it is, fixed my control driver but can’t think of anything else related?!? connection is fine going to it
@@djlouis2150 will it pass California smog after bypssing it?
I’m going to try this..I’ve been replacing the parts trying to do it right, but it’s still acting up.
Hope it works out for you. If it were a modification that was constantly affecting the emissions we would likely not do it. This modification only affects the start up emissions so not a big deal in our opinion.
Terry
Heating the cat isn't what secondary injection does. It's to inject oxygen in the exhaust system when the fuel mixture is rich upon cold start ups. All to have lower emissions
Yeah we kinda misspoke there but the end result is the same. A lot goes into making a video. Some of the mistakes are hilarious and you do not always catch them right away. You get so focused on one thing that you overlook another.
'Terry
I just bought the bypass kit ...
But I was wondering about the block off plates.
Why are the plates vital for this kit to work? Sorry if this is a dumb question
I think its because the valve was stuck open and once the vehicle stars that port needs to be closed.
Good luck with them plates if you live any place where they use salt in the winter. Still trying to get my plates in. LOL!
Yeah you guys in the snow world have lots of tough issues to deal with. Good luck!!
Terry
@@ForestToFarm Looking to install this on my Sequoia here in Minneapolis. Any luck? What happens if you don't install the plates?
@@alexdanzberger9082 I don't think it will operate properly without those plates.
Terry
Great video! I'm about to install this, this coming weekend. This video will help a lot! Wish me luck!
Thanks so much! Hope it helps you out and best of luck!!
. Question, is this a Gen one or Gen 2 kit ? I just called Hewitt and they recommended that g2 which is actually $400
@@gtrance3567 This is a Gen1 for the early versions of the Tundra/Sequoia, etc. Gen2 would be for the newer models of vehicles. I just ordered a Gen1 for my '06 Sequoia. Good luck.
I have this on my truck 2008 tundra, now i am getting the error again. did this go bad, get too hot, wondering what to do?
Not sure what to tell you. I would call Hewitt and see what their tech has to say about it. Good luck!!
Terry
Nice job gentlemen!
Thanks!
Terry
Just installed on 2006 4Runner. Works great! How does module trick ecm into not running the pump?
Awesome. Not 100% sure but it works!!
Terryt
What it the point of the knock-off plates? They seem superfluous.
The plates block the air flow when the valve is open. If the valve fails in the open position and you did not have the plates then you would have problems with that air flow.
Thanks for watching and good luck!!
Terry
I got an 05 Sequoia; so far that piece of crap hasn't given me an issue, but now I know what to do when it does!
Ha ha. Wish you luck.
Terry
Thanks for doing this video!
No Problem. Glad to help.
Terry
An update here: I was good for A few months but now I am having a mass airflow sensor CEL. Also strong smell of gasoline at start up. Called customer service and they didn’t think it was a kit rather the actual sensor. Replaced it and reset CEL. Will circle back and advise.
Thanks for the update!! So far we have had good luck with ours.
Terry
Any updates?
Same thing has happened to me. Was it your MAF sensor? My dealership tells me it is caused from the bypass kit itself.
@@michaeldillon525 was not the sensor, it was the actual kit. It took a few calls and some troubleshooting but eventually they sent out a replacement, and it resolved the issue.
@@gtrance3567 Glad you got it figured out! I've been in contact with Hewitt Tech about this. They're wanting me to test my kit again to make sure I have the voltage drop on startup. I really want to install the block off plates but I've already broken one stud and I'm sure the others would do the same.
the obd2 readers are like 30 dollars and most auto parts stores offer free use of theirs to diagnose your codes. Some require you to leave your license but last time i did it they just let me run out with it and 5 minutes later i was done and returned it.
Thanks! Yeah they will let you use one. Because we are loyal to one parts store and frequent the place they also let us use things without a license or money most times.
Terry
I just bought my 06 Tundra with 86k miles and got the p1442&p1445 codes. I tore off what I believe was this bypass lol thinking it was some aftermarket ECU bs plug in tune. Will using this bypass mess up the engine? Or does this bypass just completely disable the fan system? It’s only used on cold start ups right?
Pretty much what I’m asking is this bypass deleted the SAIC? So no more having to worry about it at all? Because I see no point in fixing it when it’ll just break again especially if you don’t even need it.
Sorry, but I’m not an expert on it. I wish I knew more, but your best bet would be to check with the manufacturer. Thanks for watching!
Hello, I just watched your video, and my by pass kit was installed just as you did yours. The problem I am having is my 05 Tundra is going into a limp mode. I called Hewitt and the tech explained to me that they are having trouble with some of the 4.7 liter engines going into a p2445 code. They are saying this is a below freezing temp. mode I have to start my truck let it warm up, once the temp gage moves showing the engine is warm I have to cut the truck back off wait 5 seconds then start the truck back up then drive away. If I do not do these steps my truck will not go above 45 MPH Hewitt state they have been working with several Toyota dealers to find a solution to this limp mode code so they can install it into the by pass kit but have been unsuccessful. The tech said its not happening on all 4.7 engines but of course it has to happen to me. Being a fire fighter it sucks to have to wait for the truck to warm up before I can take off to answer calls. So my question is does anyone else have this problem with there by pass kit or have you ever heard of the cold weather P2445 limp mode code?? I thought thats what this kid was suppose to do but Hewitt says they are aware of the problem but unfortunately they have no solution at this time.. Any help would greatly be appreciate!!!
Sorry it did not work out for you. Hope they come up with a solution. Would a dip stick heater help you get warmed up faster in cold weather? I know its not a fix but maybe it could expedite your take off time?
Terry
Did Hewitt fix this issue? I have the same code. I live in California. Wondering if it will pass smog after installation.
Great video - very helpful. Thanks dudes!
Thanks! Always glad to help!
Terry
I have these codes.... could it be what is putting my car in limp mode?
I would think so.
Terry
Dear Terry,
And the dashing duo rides again!!! I wonder however if Toyota would have have posters in their offices of the infamous gang now considered Persona non grata wanted dead or alive??? Very well done. Kind regards.
Lol! Thanks. Its still working great!
Terry
One question, (I've had mine on since 2012, still works great) should I remove the exhaust caps and clean them? I imagine all the blocked secondary air has created a pretty good crud in the pipe?
Honestly I am not sure. Brian traded that truck last February. I would call or message Hewitt. They were pretty helpful for us. Thanks for watching!!
Terry
OK, so my question is if my truck is already throwing the codes because maybe the fan blades broke or something like that on the secondary injection pump can I run the bypass kit and it will not have to be properly fixed by ripping the engine apart still ?
The bypass is designed to trick the system into thinking it is working properly. That bypass kit, when installed as we fid, at least for us, made the truck run fine with no further issues. He has since traded it for a 2021 F150. Good luck!!
Terry
The kit I bought says the ignition wire step is not needed, it didn’t even come with the wire for it to be an option. Thanks for showing the location of block off plates.
Some are made that way iirc.
Terry
You likely bought one of the cheap knock offs. They are not engineered or put together with automotive quality and we sell a lot of replacement to their customers when they fail.
@@Hewitt-tech That is the poorest form of customer service when you bash a competitor/customer without knowing all the details.
@@3wrapframe What I said was not meant to bash anyone so I apologize if you or anyone else took offense. Many are just not aware of the differences between our Hewitt Tech kit and others and often assume they are all the same. I am intimately aware of the details of the/any kit you could have purchased and feel that I can very safely say exactly what I did, so I will say it again. No other kit is designed or manufactured to the level of quality that the Hewitt Tech kits is. It takes much more than is obvious on the outside to ensure our units will last the life of the vehicle in the harsh under-hood environment.

I just recieved the kit. You stated your kit came with the wire loom for the purple wire. I clicked on the link you ordered for the 2005 - 2007 tundra. It doesnt show an extra wire loom. Sure enough, it didnt come on that kit. Have to run lowes to get one.
Maybe they have changed the content? Sorry to hear that. I can say it is still working great for us!!
Terry
Went to get a smog it indicated that he said air do I need this kit to pass the smog test
@@BUCK9110 did your truck pass smog?
Yes I did
In regards to breaking off the studs; would it be better to work on a warm or cold engine? I feel like taking off a cold oil filter is easier than warm so no sure if the same logic might apply here
Good question. If the engine were warm you may run the risk of getting burned. However I have known of people heating metal objects with a torch to expand the metal when trying to remove other metal objects from the first metal object. I am no expert there. Sorry.
Terry
Does anyone know where I can purchase this kit?
Thanks for watching!!
Check in the description of this video.
Terry
I need to do this on my 4runner.
It worked out great for Brian. He traded it for an F150 close to a year ago. Thanks for watching!!
Terry
Excellent video, gentlemen. Gotta do this for our '06 4Runner. Have you fellas replaced the headers on the Tundra yet?
Thanks. Have not done anything to the headers. Is there a problem?
Terry
Thanks ! Hell ya
😁
Good product...Be careful though on those screws where the plates goes...one of mine(outside one) snapped in half and now I have a big problem. There is no way to change it or fix because no room to work. I have terrible noise and i am out of solutions. I may have to take the engine out to fix that....
I hear ya. Would you be in a northern state? Things tend to rust up that way. Ours was clean as a whistle 😁 i grew up in Michigan. It would probably have been rusty there. Good luck!!
Terry
Going. To install when it stops raining hopes it works
Good luck. It has worked well for us thus far. We would love to hear how it turns out for you.
Terry
I have this code, however, I was wondering what the symptoms that you guys are running into with the performance of the engine with this code present.?
Brian was lucky. The only thing it did was make a very obvious vacuum sound when you first started it. Then it would make a kind of sucking sound as the valve apparently closed. He has traded that truck on an F150. Thanks for watching!!
Terry
One cuestion this kits work for toyota tundra 4.7L 2007 and were put the plates on you put or under the manifold
Not 100% sure on that. I would contact the Hewitt company. They are very helpful.
Terry
Great video guys! Have you had any or heard of any problems with the bypass kit having problems in cold conditions? I've seen a few things about the system still dropping into limp mode in colder areas. Mine was making the same noise as yours but had no codes. As a diesel mechanic thought no big deal decided to replace everything and now it all works but I have a code that will not go away lol....what a joke right. Ive tested everything and now see toyota has a tsb to replace the control module for $200+. No way! So after blowing all that money away I'm just going to delete it. Thanks guys
Thanks! I have not heard of any problems although its possible I missed something here or forgot it, ha ha. Lots of comments with all videos considered. I can say we have had zero issues since installing it on Brian's truck. Man I wish cars were as simple as back when I was a kid. I fixed everything with no real efforts other than basic mechanics. Now you gotta think like a super computer just to figure it all out, lol.
Terry
Thanks for the knowledge. Yes having all these electronics can be nice but I think we are shooting ourselves in the foot as well. It's hard to belive how far technology has come along and how fast it's still growing. Thanks again brother and be safe out there! Thanks again!
@@mrfarmer1903 You are welcome! Thanks for watching!!
Terry
I didn’t a get a CEL when it failed. I was sitting in a parking lot then the truck just shut off. 4HI light was the only thing flashing.
We were lucky and it never shut down. It just made an air suction sound when first started each day. We knew something was up. Took it to Advance auto and did the analyzer. Then Brian found out how expensive it was to fix and stated looking for a work around when he found this solution. Glad he found it.
Terry
This is my concern. Can I ask what year your truck is? Thank you
I just did this, and for the first time ever, I wish I had smaller hands and forearms.🥵. Those two pipes are awfully hard to get at.
Yeah its a bit tight. Worth the effort though. Thanks for watching!
Terry
@@ForestToFarm thanks for posting!!
‘‘Twas super helpful!
@@Lucas-pv2wn Awesome! Thanks!
Terry
I'm guessing this works on 4runners as well? 2005 2uz-fe vvti
I believe so. Any of the V8 engines on their platform can have this issue, and I’m pretty sure the 4runners have the same engine as the Tundras. Definitely check with Hewitt 👍
Thanks for watching!
Does the air pump only work on cold start to heat cat? Does it turn off after cat is warm/hot? It must be getting temp info somewhere.
I believe that’s what it does. It pulls engine heat to heat the cat quickly, then it cuts off (from what I understand)
Thanks
Brian
I have a 2007 sequioa giving me a p2445 code and track and the other light it goes on limp mode but then I erase the code and drives fine will this fix the problem?
I would check in with Hewitt. They can tell you much better than myself. There are so many possible problems that can occur .

Forest To Farm I bought the gen 2 3 vale bypass $400 and didn’t work still codes come on
@@shopking6989 Humm. Not sure what is going on there. Could be other issues we are not aware of? We have been fortunate that this is still working great for us.
Terry
Love it thanks
Thanks!
Terry
My 2006 tundra roars when it first starts up. Assume this is the secondary air pump pushing air loudly? No codes. Besides codes what else will have problems if the secondary air system is not fixed ?
Right off the top of my head it would eventually start going into “limp”mode which basically makes it run super slow. We are not experts on this system but did the research to get it done. Wish I knew more. Thanks for watching!
Terry
I have this exact sound but my codes are p0441 and p0445. Is that the same thing?
Honestly not sure. Brian traded that truck off last winter for an F150. 😁
Hey there, when you first cranked it and that high pitch whistle noise settled, it made a weird rattle noise which is also what mine is doing as well. It seemed to go away after you installed the bypass kit. I’m just wondering if the sais would have anything to do with that or if it’s internal? I have a video on my channel that you can hear the noise very clearly. I haven’t been driving the truck much lately so I’ve put off on fixing it. But the weird thing is, is that it isn’t throwing a check engine light, it does have a maintenance required light on though. But if you have any idea on what it could be I’d greatly appreciate that, something like this I can fix myself without having to take it to a mechanic IF it has anything to do with the sais. Thanks!
Yeah it was the air valve making the noise and it did clear up.
Great video. My engine makes similar sound, tough idle and suction sound. Threw CEL p1441 p1442 Got it scanned and now the CEL is off. But I still think it has the issue. Safe to say I need this? Did your cel go off? Were you able to pass an emissions test? Thank you great video.
My CEL did go off and on several times over a few months. I have not had an emissions test, they aren’t required for our state. Thanks for watching!
If got mine for “off-road use only” in cali dw
Thanks for watching!
Terry
Mine just started throwing the code. Any idea how long I have before I absolutely HAVE to do this? Planning to do it in a week or two, but like you said, I don't want it to go out on a north GA road in the next few days. And in the meantime is it doing any damage to my engine?
It was acting up for about a year and a half for us. We were lucky it did not go into limp mode sooner. I do not think your causing damage to the engine but I am no expert on the subject. Good luck!!
Terry
@@ForestToFarm yeah I guess the uses car lot must have cleared the codes before letting me test drive it. But I ordered this same kit and will be following along on the video while I do my own!
@@zhukel_marimasko They can be deceptive for sure. Stinks!
Terry
@@ForestToFarm just finished doing mine! Did take off the drivers side tire for one plate, but realized on the passenger side that I could just turn the wheel. But all in all it was as simple as y'all made it look! Any other changes I should make to my 06 to maintain that "bulletproof Toyota" status?
@@zhukel_marimasko I can not think of anything. You may want to change the timing belt if its not been done. That is up next for us. It can be overlooked until its to late if you are not careful.
Terry
So question installing this bypass kit doesn't effect the motors power? And is it bad to have em on a long run especially blocking those 2 sides of the motor?
No effect on the power. I do not think its bad at all. had zero issues until I sold the truck this past Feb.
Good luck!
@@ForestToFarm and how long did you have it on until February when you sold it
Anyone have advice for rusted bolts for where the block off plates go?
You must live up north. That salt is rough on things. My 99 F150 is pretty much rust free down here in the south. Only thing I ever used is WD40. Maybe try to get something up against it and bang on it with a hammer? Wish I knew more. Good luck!
Terry
what if I snapped off one of the nuts of the exhaust?
if you don't have catalytic converters, do you still need to do the mechanical step at 17 minutes?
I would say absolutely needed. Its what you are "bypassing". Good luck!!
Terry
If I do this in California will it pass smog
I honestly do not know but I would think its very possible no.
Terry
Good video I have a 2005 Toyota sequioa air injection valve with the check engine on do you think the sais bypass kit works for my sequioa? thank you
Yep, it’s the same engine. Thanks for watching!
But I don't know where to order my bypass kit. Thank you for get back with me.

Code P2443 is showing up on my truck, also with the kit will I pass emission inspection?
Sorry I can not answer that question. No idea. We just sold the truck about a month or so ago. Got a new F150! Love it. Good luck. If it still showing a code seems like you still have something wrong.
Is there any potential for this to cause damage to other parts of the emissions system? Such as the catalytic converter?
I would feel best referring you to the manufacturer. All I can say for sure is we have had zero problems since installing it. It has done everything they said it would and saved us a chunk of change.
Terry
I had this on my truck for going on 4 years, no issues. Passes inspection every time.
@@zermus7040 Great to hear! We have had good luck as well.
Terry
@@ForestToFarm I would also add, I to had this happen to my 4runner (v8) and I brought it into the dealership and the guy who worked at Toyota was like... homie, just put this on your 4runner instead because you shouldn't have to pay 2,500 dollars. Also I was blessed that Washington State just stopped requiring admissions tests. Boom baby!! hope it worked out for you.
Do you guys have any issues with limp mode when it gets cold?
Nope, never have. I’ve been very fortunate. After installing this system it’s worked like new.
Will this work for an 07 sequoia 4.7L with P2445 and P0418 codes?
Wish I could help but I honestly don’t know.
Terry
@@ForestToFarm No worries. Thank you anyways
Can it still be used in 2010 Toyota land cruiser
Honestly not sure about that. I would contact the company, they are very helpful.
Terry
hello. can you tell me where i can buy this bypass? I have a 2006 Toyota Sequoia.
Hey. Thanks for watching! It should be linked in the description under the video. Brian traded the truck last year and I honestly do not remember off hand.
Terry
Would I be correct, if you have the p1442 & p1445 and that means valves are stuck closed. You would not need to install the block plates? The p1441 & p1444 being stuck open, you would need to install blocking plates?
Great question. In theory that sounds like a great idea. However I am not an expert on what would happen if the valves suddenly started working. You might could ask the manufacturer and get a more informed response. They are linked in the description below. Hope that helps and sorry I do not know more. I like your way of thinking!!
Terry
Yes you need to. There is a couple of pressure sensors on the secondary air system that would trigger the check engine light if those plates are not installed.
@@neverstoplearning382 Thanks for the input!!
Terry
@@neverstoplearning382 Yes! Thank you!
Man i have this problem, this kit, didnt use the plates because a bolt broke on passenger side tube for plate, i left it alone, installed the harness , been 2 years in a harsh winter area and never had another problem again all while not using them plates! So screw em! Lol. I also don’t remember the codes numbers but it was this issue
I have that sound but no Check engine light or codes. Does this kit cause any problems after you’ve driven the truck a while?
So far no problems!
Terry
I had the cel but it’s off now.
they say an air injection failure puts your truck in limp mode to prevent damage to your engine. Is that true or just a scare tactic?
I have heard other people say their trucks went into limp mode but the truck in this video never went into limp mode. It just made a suction sound when first cold started for 30 or 45 seconds.
Terry
my truck is a 2013 tundra. maybe your 06 model doesn't put it in limp mode or what do I know. my truck is making that same noise on cold startup. I just want to know if this is something I can try before having to shell out 2 grand. I looked at my truck and those blocking plates look like they are more easily accessible. Im also reading that some tundras are getting extended warranties on the air pump because of high failures but mine isn't one of the :(. bummer I just paid off my truck last year.
I would contact the company. They are very knowledgeable on the subject. I am just not sure on all the details and I do not want to steer you in the wrong direction.
Terry

It depends on the trouble codes that are being thrown by the system. Some cause limp mode and some do not.
What options do I have if the nut/bolt snapped off while trying to install the block off plate. I hit it with penetrating oil, but live in New England with so much salt and corrosion, they just sheared right off. Local muffler shop said it can't be drilled and tapped without taking the engine out. Any other creative solutions? Can it be blocked where it connects into the exhaust manifolds? Or under the intake manifold where it comes out of the pump? I realize if I got that far, I should have just replaced the pump altogether but do not see a way to drill and tap as is.
Man that stinks. Salt is not a cars friend. I have no valid advice here. Never had that problem. If you can find a way to block it off seems it should work. Tearing that manifold down seems like a lot of effort but may be the way to go. I would ask Hewitt and see if they have had this problem. Sorry I am not more help.
Terry
C no I haven’t. If you follow those pipes up and to the back of the intake manifold, you can put the block off plates there. Same connection and likely less corroded than the connection near the manifold. However, there isn’t much room to work back there (it’s at the back of the intake manifold). My switching valves are stuck closed (that is the only code I had) so just going for it and hoping that them being closed is good enough to keep any exhaust from backing and damaging the sensors. So far so good after 1k miles.
Well im late here but ive got an 05’ tundra dc and had this code, i bought this kit, had a bolt break on the pipe for the knock off plates on passenger side, so i didnt take out any more bolts and i left them pipes alone, installed the wiring kit, and have never had another issue and never used the knock off plates lol. Its been 2 years now, i live in northeastern Pennsylvania and never had another issue.. so screw them plates!!
