Tundra Won't Accelerate FIXED - VSC & Engine light on
HTML-код
- Опубликовано: 28 авг 2024
- This is a quick video showing the basics on the secondary air pump system that causes Toyota vehicles to throw a check engine light and go into limp mode - The problem is the secondary air pump(s) draw in moisture and fill up the housing with water over time. This causes the pumps to short out & the air injection valves to rust & sieze up in the open position. This is why your vehicle might be stuck in limp mode and have the VSC & Traction control lights on. If you are unable to accelerate on the highway & the check engine light is on, it is most likely for the secondary control valves or the air pumps. This will help show you a break down of what is going on & hopefully help you get you Tundra or Sequoia back up & running

This is happening to my 07 now-ima do this-I’m at 402,000! Ima take this baby to 1,000,000🤘🏼 thanks for making this
I had the same issue, purchased the Hewitt Tech bypass kit for $450 and in about an hour it was installed and the problem went away. I would recommend this kit to anyone who doesn’t have to worry about passing emissions testing in their state.
I was looking In to buy that
@@garysmith9017 it’s cheaper now and they have an updated Gen 2 kit. I have the Gen 1 and it works fine for me.
Drilling a hole, then using a penetrating oil like Kroil sprayed into the valve will fix the issue. Poorly designed and poorly managed by Toyota. That worked for me
@@joeybuckles8404hey joey i just bought a gen 1 kit for 195$. Did you just buy alone the gen 1 kit and installed it like that? I called Hewitt and they’re telling me I have to buy an extra connecter for 100$. Looking to see if you just bought the gen 1 kit alone 195$ and installed it like that. I’m putting it in into my 2012 4.6
@@bullredfish12hi do you have an update on what happened after drilling a hole did you have any cons ?
Thanks for sharing! my Tundra did the same exact thing as soon as I left home, your video saved me $$$$ two pumps $160 plus 1 hour of my time! Now the truck is back on the road
Hello friend please quick question my car stuck in 4th gear and no power it barely moves but if I disconnect the battery and rest it the car gets back to normal it goes about 50/60 miles and the problem comes back i am very upset I couldn’t find a solution
Do you have the parts number to all the parts or could you steer me in the right direction
Hey @john, thanks for making this video. I'm no mechanic and never even changed my own oil, but this gave me the motivation to attempt a repair myself. Rats had chewed the wiring on my knock sensors and I had to remove the air intake manifold to reach them. Your vid showed how this was possible. I saved $1,500 in repairs and my Tundra runs like new again. Kudos!
Thats beyond impressive for someone who has never changed their own oil
How much were the parts? Did you replace the pumps also?
@@rjayfitness No pumps replaced. Just the wires to the knock sensor. $2 total.
Had to do it again a few months after. Now I sprayed some pepper spray and no more issues.
@@stephanecome4234 where did u buy the wiring? I'm having the same problem.
@@thetruelifelover It was my local O’Reilly or Advanced Auto. Any of them should have it or able to order them.
Had that repair done on my 2008 5.7 which was out of warranty. Check engine light with two codes and bank 2 however vehicle never went into limp mode. In fact check engine light came on right before a 2000 mile trip. Toyota said it was safe to drive for the entire trip just kept the RPMs low.
Total cost was 2600 and I reached out to Toyota Motor Corporation for assistance and they cut me a check for 1900. Design flaw
Hey Chris how old was your 08 when it happened? I’ve heard these specific parts are warrantied to 10/150,000 because it is a known issue. Just happened to my 08 with 136,000 so I am probably out of luck with it being older than 10 years.
@@nicegunt let's see the year is 2021 I had the repair done if I'm not mistaken in 2019.. it was past the 10 years... what ended up happening was since it's my third Toyota the service manager assisted me on what to say to Toyota Motor Corporation when I gave them a buzz to reach out for help.
Toyota Motor Corporation are extremely friendly people and there's a good chance if you're a valued customer and you've bought more than one truck from them they will take your name and number and get back to you in a few days after they do an investigation. That's exactly what they did with me. Since it was my third Toyota they decided to cover 80% of the cost. They just send the check directly to the dealer who's fixing your Toyota. You can only get this assistance through Toyota Motor Corporation if you take the truck to a Toyota dealer for the repair.
In my case I had all the services and minor repairs done at the same toyou do so they had my whole service record. It's a very expensive repair if you don't have assistance but there's another option...
I did a lot of research and there's a kit you can buy which will bypass the secondary air pumps . From what I understand the kit is a couple hundred dollars and it may even be able to be put in by yourself I don't think you'll need the dealer... there's hundred the RUclips videos on how you purchase the kit and where and they talk you through it step-by-step but basically it'll bypass your secondary air pumps and then you just go to the dealer and have the check engine light turned off and you'll be all clear so that you can get an inspection sticker. Basically the truck will run just as it did before you just won't have secondary air pumps since you'll have the bypass unit... if you don't do the bypass unit then you're going to have to do the repair through a certified technician just use caution and don't drive the truck very fast and high RPM while that check engine light is still on...may go into limp mode and if it does it cost you an arm and a leg to take it out of limp mode and then still have the repair done. That mode will activate to protect any components from being damaged..
Good luck bro
@@nicegunt if the dealer does your repair then the new secondary air pumps will be the updated models that have the little covers and slats so that water can't get in. It was a simple design flaw that they put on the 08 and moisture gradually made its way up all the way to the pumps which are located at the top of the engine... you're looking at no less than $2,500 and I've even heard another States depending on where you live and maybe as high as 3500 to 4000..
Very kind of you to respond with all of the detail. I truly appreciate all of the advice!
@@nicegunt welcome
Thank you for posting it. You are a star. I have the same problem and planning on drilling small holes to fix it. It is a brilliant idea.
Do any of you have any updates on the pros and cons of drilling a hole I have a feeling it will have side affect but then again I don’t know the exactly purpose of those rubber boots
Guys, you might want to try this first if your check engine light is on and your 5.7 tundra is weak and won’t run over 50 to 60 mph, My tundra had these issues so i floored it a couple times while driving, problem fixed, also took the positive battery cable off and put it back on to clear the cel. So far so good, may be worth a shot before spending a ton of money.
Very well explained video . I had same issue with mine ,but with the 4.7 liter engine . You don’t need to take intake manifold off . They are located on the left and right side of engine . Very easy to change out . I also learned to buy OEM parts because the generic ones last a year if you’re lucky .
You're so awesome!! This is actually happening to our 2010 Tundra while we're on vacation in Destin FL. We don't even live in FL! I wish this was happening while we were home 😫
But still appreciate your video!
Having this same issue on my truck tried to start it last night and it had an air sound to the engine and seemed like it was running rough and the VSC and check engine light came on. Probably gonna attempt the repair myself as i dont have the money to let a shop do it.
2009 sequoia problem fixed, many thanks
Hello, sorry, how can I request that part?
I had the same problem. Fortunately, it was just a 10amp fuse. ALWAYS CHECK YOUR FUSES FIRST FOLKS!!!
Fuse is popping for some reason. Most likely you're getting water in the air pump and it's causing the air pump to work harder and causing the fuse to pop so at the very least I would drill some holes on the bottom to get the water out and to do it properly you need to replace the one way valves so that air doesn't flow on both directions. The reason I think water gets in the pumps is because the valves fail and exhaust is going into the air pump and exhaust has moisture in it.
Man, thank you for making this video. I had no idea the location this pump. My code is P2445. I have a 2007 tundra limited. So far I replace the starter, that was a nightmare, water pump, belt and tensioner, radiator hoses. Thanks again for making this video.
I had this problem both in and out of warranty on my 2008 4.7L Tundra. The dealer had to fix the problem the 1st go-round. Hewitt Technologies fixed the problem with their plug-play SAIS computer the 2nd time the problem occurred. Still have the truck and drive it everyday.
Just tried this yesterday and looks like it didn’t help
@@danielmejia6219 You're saying you bought and installed the proper component from this company (www.youtube.com/@Hewitt-tech/videos) and your problem was not resolved?
It helps if you remove the cowl, wiper transmission, and the tray it sits in. Magnet finger also help.
Now that we're slightly in the future. You can also just let the system finish its cycle and use either a proper code scanner or BlueDriver and clear the code once the truck is no longer "Cold" and it can be driven as such. Though, properly fixing things is also great. The parts are mightily expensive.
Apparently that bypass module kit makes the check engine light disappear. I myself ordered this kit last night as I have a p2442 code. Hope to put it in Monday.
Did it work?
Any luck with it?
Same codes here, garage reset and was all good until codes reapears...
Did it work?
Most likely you're getting water in the air pumps. I would drill some holes on the bottom line you did to get the water out and The reason I think water gets in the pumps is because the one way valves fail and exhaust is going into the air pump and exhaust has moisture in it.
I wonder if a cheap one way hair valve that hot tubs and spas use on their air pump systems would fix the valves from leaking back to the air pumps. They sell one and a half and two inch pipes that look like about the same size as the failed valves you show it in the video. Could be a $20 fix without having to dig out the old Air valves. But the way you did it it's the right way and it's going to last for a long time especially now that you have holes in the bottom.
I drilled holes in my rubber cups thinking there would be water in them. They were dry & I’m still in limp mode.
Your truck looks amazing
Toyota made an absolute garbage design with their air pump systems for the Tundra.
That is a very common problem on that truck.
Got a by pass kit on ebay for a couple hundred. It been great for years. Truck doesn't need that that part. It was to appease EPA
@@aekuterbach1 do u still have link of bypass kit? My VSC light just started flashing yesterday.
@@willietownsend3547 I don't have the link, it's been years and still no problems. Look up tundra bypass system. It was a about 3 hundred. Totally works!!!
How has this repair held up for ya, thanking about tackling this project today. Thanks for the video!
It's an easy repair looking back. Truck ran fine for the next 6 months. Sold it to buy a newer Tundra.
Was running great when sold
Anybody still have link to bypass kit? My VSC started flashing yesterday on my 08 Tundra.
Replaced Secondary air injection system, the air pump for it is fine.
Still throwing codes and check engine light. Reset and nothing stays on.
I had the same issue, youtubed it, came across an old dude that just took both battery cables off for a few minutes, put em back on and voila, I did the same thing and all the lights went off, no $200 fix at all.
Yeah I did that a few times also, it will hold out for a few days but will eventually come back on
Good video ... Did u have to replace the gaskets on manifold or can u just reuse them ?
Truck doesn't need that part. It was to appease EPA regulation. By pass system works awesome 😎
can you tell me which one exactly
thanks
I have a 2010 Toyota tundra I’m having issues with the acceleration it won’t go past 50/60 miles on the highway can you tell me what is happening or what I can do to fix it. Please
Can I not just drill a couple holes in the bottom rubber without having to remove the pumps?
It's really helpful thank you 👍👍👍👍👍
Always check the muffler bearings.
I always check the tail light pressure.
Very good, importan information intelligent and proactive! Thank you so much
good job
Hello, Code PO419 , check engine light, and Wont Accelerate Above 50, is this code for the same issue ? Thanks.
Id like to know too.
Garage said kinda error about air intake or injector (running smoothly as usual) but wasnt sure...
Still canot accelerate fast and go above 80 km/h too
That's not a vacuum hose, that system is lightly pressured when the fans are on. It's a vent for the solenoid plunger.
Approximately how much would a mechanic charge for something like this? I don't want to get ripped off.
Toyota have warranty on the air pump for tundra under 150 000 mile ,did it couple month ago
I call the dealer and they said it went out in 2019 I have a 2008 Toyota Tundra having the same problems slow acceleration I'm trying to figure out what's wrong with mine can anybody help
What year is your tundra

I got a 2008 toyota tundra 4.7. Code p2436/p2438. Secondary air injector system. Bank 2 .. I don't know which part causing it.. bypass kit on but check light still on with traction blinking
How does water get in the intake?
Great info ..thanks
Hi! I’m having issues with my 2011 tundra. No mechanic is able to find out what’s wrong with it. It starts up normally but it loosing power when I accelerate. The only lights that come up is A/T temp oil and check engine light. I let it cool off and it starts again like nothing happened. When I took it to the mechanic, they put the coder and nothing comes up. What can it be?
Just purchase the bypass harness put the shims in all good
I have the same lights on but mine isint in limp mode i can still get it up to speed fairly ikay but for sure has an issue it shakes when on light throttle in between 30 to 40mph anybody had this issue?
So you dont think putting tiny holes at the bottom of the pumps won't suck more water into the system
Nope. Its just like drilling holes in the bottom of a 5 gallon bucket, let's the water drain out. The truck is still operating properly to this day
@@JohnCalebWarren bypass is the only way
Wich bypass?
I got a 0101 code no matter what I do New Maf cleaned air filter no leaks it pops up. I had a dump exhaust after muffler and added the axle back to it. Do you think that’s the cause? Truck is supercharged and tuned on Orange virus. Sometimes I get a crank position sensor code also. 0013 I think. Let me know what you think. Have a k&n filter as well with the stock air box mod.
Thank you so much
Please tell me if those are after market wheels??!!! I need to know. YOU HAVE MY SAME WHEELS! tHEY CAME ON MY TRUCK. WHO MAKES THOSE WHEELS.? I NEED THE LITTLE HUB CAPS, mine corrodied. Thanks. Are they are were they stock wheels??
What a bunch of shit to go threw smh. I thought Toyota was supposed to be better than this.
Do you have the parts number to all the parts i have the 2008 with the 5.7 engine. Or could you steer me in the right direction
2007 Toyota tundra 4.7. P4019 code. Tested the pump. Seems like only 1 pump which works. Still in limp mode. Any advice?
Look the video
Hi. Thanks for the video. The secondary airpump; is that suppose to rotate when ignition is on? Mine is not. I am currently troubleshooting a C1201 code that has the same exact symptoms like your truck - vsc flashing, ABS on, engine light on. I have a 2007 tundra ltd. Please help.
Did you ever figure it out
Same issue on a 2008 4runner,
If i by that bypass kit i just clip it on or is there more to it after that ? No motor knowledge smh
It's pretty much just a direct Plug & Play. However there are some exhaust block off plates that are strongly advised to install to prevent further damage to the valve assembly. If you just install the module kit without the block off plates it will still work and run correctly without a check engine light
I took the ECB-1 fuse out and the check engine light is still on.
They fixed a few yrs 3k problem that had warranty
I blame Obama
Excellent
I have the same issue, but I replaced the check valve for the bank 1 side, check the pumps free of debris and water, tested both pumps, went to clear the codes and my scanner says permanent next to the code can anybody help?
Did the lights ever come back up?
Once but it was user error, cleared the codes & they never came back
i have a 07 tundra and it wont start.. i get the code c1201.. any help?
A stuck open Valve will cut power... a stuck shut valve will turn engine light on. An give you 10 mpg cos it Messes up the Second O2 Sensor...Making the truck run almost like a choke is on. :( I am not a fan of Toyota after this being my 12 one... this is by far the worse TOYOTA I've ever owned.
Excellence !!
Will this work on a 5.7 tundra?
I had that same repair done on my 5.7 2008
If you're talking about the bypass I heard yes it will work
Is the fix still working?
Nasty, letting your kid touch that
I need your help
What but 2008 ,4.0 v6 engine same problem
So I had code 2442 replaced all and now I have code 2440
Jj Bolthouse buy the bypass kit
Молодец брат
Your car looks really new, how could that happen being that new
It's not new,those are the previous models and are 07 to 11 approx. So that many years is gonna give you problems due to wear and tear. I just fixed mine on that same issue and by looking at the truck,you could swear it's new, but mechanically, the parts get old and break down.
Just spent 3000.00 at dealer for my 2007
Ouch!
