I'm looking at buying one of these. 08-09 Tundra. I've read this is a common issue. Despite this is your friend still happy with his truck or are they riddled with problems?
I have a 2012 tundra 4.6L at 130k miles. I had codes p2442, p2447. I ordered parts from Amazon and after watching this video had it done in 2.5 hours with no experience. Thanks for making this video, It helped a lot.
I found this video helpful and would like to offer some anecdotes. The Tundra was giving the P2445 code, indicating a Bank 1 Air Injection Reaction Pump failure. This is one of two pumps located between the front right wheel well and engine compartment. The compartment holding the two pumps is on top of and in front of the front right (passenger side) wheel and tire. You will have to remove the protective covering between the wheel well and engine compartment with wire cutters or snips or a fastener remover. There was one unique plastic (rubber) fastenter, that required me to use a drill bit to remove it, since it wouldn't unscrew or release. I just put a drill bit in my drill and drilled through the middle of the fastener, and pulled out the whole thing. This video provides most of the other info so you can dismount the pumps and replace one or the other or both. The location of bank (pump) A and B, since there are two of them can be confusing. The pump located toward the center of the vehicle is bank (pump) A and the one located toward the outside is bank (pump) B.
Mine went out in my 2010 tundra with over 130k on the engine and Toyota fixed it for free. They also installed the newer snorkels that curve 180 degrees. I was shocked because the warranty had been long expired. They told me it was a known issue and a engineering problem with the old style snorkels. Snow pack would build up in the wheel well area and melt. With the old snorkel like your truck has, the snow would melt and get into the pumps and ruin them. The new design is supposed to eliminate that issue. Thanks for the video.
Mine is 2010 4.6 L with 76k miles on it. Called Toyota usa to complain as a 2nd owner since 2017, and they told me its not a recall. It was service notice which was mailed out once only to original owner in 2012, and expired in May 2020! and there is nothing we can do..would you please let me know when exactly you took it and had it fixed and what dealership fixed it, I live in rock hill, SC. I have code p2440. 2 mechanics told me only dealer can fix it.
There’s a individual/company that manufactures and sells a by-pass kit consisting of a module and wiring to deactivate the air pumps (Tundra Hewitt I believe ?) This allows the ECU to register the air pumps as working, but allows vehicles to legally pass emissions. What destroys these air pumps is moisture being captured at the bottom cup of the motor and then it seizes up and sets off a code tripping the “money light” on the dash. Some Tundra owners choosing to install new air pumps change to the revamped snorkel from Toyota and then drill 1/8 hole at the bottom of the cup to drain any water that might enter the motor housing.
Hi there, your video is 2 years old how those Amazon pump have hold up so far. I need to do the same thing but on auto-zone i188 plus tax just for one.
Per another video, you might have to also replace the solenoids at the back of the engine after taking off the manifold. Alternatively you could install the 3rd party bypass kit.
Will it matter if by accident I plugged pump on the wrong plugs like pump 1 on pump 2 and pump 2 on plug of the pump 1? Installed the pumps as the code said pumps and I did the valves last year
your thinking of the secondary switching valves that are under/behind the intake manifold. theyre up against the firewall this video shows the secondary air pumps they look very similar as well
Good video. Looking at a 2007 myself and am tracking down some of the major problems and fixes. Two questions 1. What impact wrench is that and 2. If there are no code lights on would it be beneficial to drill a small drain hole in the existing canisters to drain anything that might be in there? I liked and subbed for ya......
Have you had any problems with the installation now that you’ve been driving it for a while? I had a mechanic at an actual shop work on it and replace the pump for me and now I’m having an issue again. Are the after market parts working for you?
Injects air into the exhaust to help the catalytic converter heat up to minimize emissions, more so during start ups when engines are running rich. Many other manufacturers use them for their vehicles and some even use a mechanical pump that’s belt driven to do the same as these electrical driven air pumps
Just watched your video, about to change mine. I'm seeing A LOT of complaints about the parts from Amazon crapping out and was wondering if yours still work? Thanks
I've got a 2010 Sequoia 5.7 and with a code P2433, "pressure sensor circuit high". I've been searching high and low and cannot find the part number or where it is located to replace. Anyone have any idea, thanks.
Mine came on literally an hour after I scheduled my inspection. Found out this morning it came up P0418 and P1605 Is it 100% these pumps or is another issue possible? They cleared it and said drive 60miles, see if it comes back. I made it 200yards lol. It's running fine though, seems full power just the stupid light is on.
Alright man, BESIDES THE NOISE of the failed pump, did you have any other problems that occured along with it while driving?

Hi I have a 2008 sequoia 5.7 , code P0418, are this air pump are located at the same place has the Tundra ? Thank you for the video ,..
thank you!....i would say yes on the location
by just replacing these pumps it fixed the p2442 code? you didn't have to do anything under the intake manifold?
After replacing the pumps use a code reader to clear the code
It is recommended to replace the secondary air valves as well. This an expensive repair im thinking about just doing myself.
Is there one underneath the intake?
