2005 Toyota Sequoia P0418 P2445 P1445

This truck problem escalated quickly. From a possible transmission, to a transmission, shift cable, detent switch, to a host of secondary air injection problems. It's a review of work already done, questioning the process and sharing a lesson. Hope you enjoy.

I think that you handled this vehicle as good as you possibly could have. Great recap, too! I hope you’re feeling better, Corey!

[@SAAutoRepair]

And thanks for your help. How'd you like that code setting criteria?

[@JoesAutoElectric]

man, watching this I can feel your pain. Some jobs are nothing more than a test of your will. Good on you for sticking with it. Having a customer who understand helps quite a lot too. Great video my brother!

[@SAAutoRepair]

Oh man, the quality of the customer is the only thing that made this bearable. Almost like a job that would come out of your shop. Thanks pal

[@toddrabb1892]

I have an ‘05 Tundra that started doing the same thing. P0418 and P2445 codes. I’m a shade tree mechanic and this is my personal vehicle. At first when I cleared the codes it would be fine for 2 weeks to a month. Now I have to clear them daily to drive the truck. BUT once I clear it it runs like a dream. FYI THIS IS A DAILY DRIVER AND HAS 435K miles… considering trying a bypass kit. GREAT VIDEO!!!! I feel your pain brother!!

[@BobbleheadHomestead]

I bought a 2005 Sequoia a month ago. Had timing belt, tune-up, new tires, and all kinds of stuff done right away. Then it went in limp mode where if I floored the gas, the rpms would go up, but it wasn't accelerating. Wouldn't accelerate up hills. Took it to shop, they did the 2nd air pump replacement whatever for $900. Two days later it is back in limp mode and my research has led me here. I'm hoping you just saved my bacon and this is the fix. I just bought an 05 Sequoia junker for a donor car a few days and now I hope it starts paying off.

[@diymisfit_Mechanic_UDX404]

WOW, you pulled your hair and mine fell out. What you went through would stress anybody out. Glad your lobotomy procedure went good. 👍

[@SAAutoRepair]

I'd rather have a bottle in front of me, than a frontal lobotomy. 😂😂. Good to see you sir.

[@orville58]

There’s always one that makes you regret ever picking up a wrench lol it’s always a bad idea when the customer diags joe did a video on it but sometimes it’s unavoidable everything you did after you got the vehicle was spot on thanks for sharing your knowledge and I hope your health is good

[@SAAutoRepair]

My health is good sir. Thanks for the concern. I never regret picking up the wrench. I truly love what I do. Appreciate you sir.

[@ismarmeskovic]

customer or other shop diagnosis usually leads to the bunch of problems,anyhow im glad you manage to fix the real issue!trust no one,lesson learned.cheers!

[@SAAutoRepair]

It wasnt as much a customer diag as it was just a bad decision to hold of off on the proper diag because he thought it was going to be bad. All worked out and I appreciate your support

[@andrewk778]

It was nobody’s fault. It is an older car from the rust belt with high mileage. You were unable to test drive to test/verify. It was nobody’s fault. Thank you for sharing. It is interesting to see what you go through with some repairs.

[@SAAutoRepair]

That was my point of sharing. Many folks watch these videos and think we bang them out in minutes. Video editing does wonders for time management. Sometimes we ALL run into struggles. Thanks for the support pal.

[@johnturner8829]

Interesting case and great information. Thanks for sharing this with us Corey. Keep up the great work.

[@SAAutoRepair]

Thanks brother.

[@ThePracticalMechanic]

What a pain Corey. I can see why they replace the whole system when under warranty. Multipoint failures are so hard to diagnose and the incorrect SI doesn’t help. You persisted when many would have given up. Nice work.

[@SAAutoRepair]

And that;s not just under warranty. That's their repair regardless. Typical Staten Island Express multi point failure.

[@darakieng9374]

I’m in the same boat. I was going to check the diverter valves in this morning. Now I am confident that is the issue.

[@Hammer7442]

These parts will go bad again, I know. 2006 Toyota Tundra second time I went with the Hewitt Technology SAIS bypass. No more problems and no more P2445 code or limp mode.

[@billyyoder8171]

Thank you Corey. Good job. Have a blessed and safe week.

[@SAAutoRepair]

Thanks Bill

[@user-bf9zm9ld6i]

Hi Corey thanks for the video I have a similar problem P0418 and P2445 I replaced the secondary air injection pump but it wasn’t original from Toyota, at the beginning I thought I fixed the problem but after 150 miles the check engine came again

[@lovejules007]

Wow! Yeah you did great! I have a 2007 toyota sequoia . Dummy lights as i like to call them now came on to warn me limp mode is coming very soon. Neighbor came down, code reader said P0418/P2445 (stuck in closed system A) . Quick research to get out of dummy mode unhook the negative charge on the battery but itseems i can just disconnect it and be done! Im so hoping that is the case. Otherwise after watching your video i will start with the solenoids first! You sound like you are too far north for me to get to your shop 😉

[@lovejules007]

*injection to intake.

[@yvonnelee4396]

Thanks for the entire story. I’m the analyst type so I like to know the background stuff! Thanks for sharing!

[@SAAutoRepair]

Funny how often I get comments that I ramble to much or I should give the "silver bullet" fix. It's like too many people aren't interested in the how and why. So I really appreciate your comment. Thanks you

[@yvonnelee4396]

S & A Auto Repair I truly understand those type, too. They are the ones that can’t catch a break because everyone and everything is the reason that all the bad things happen to them. Don’t worry about those types they are in if for what they can get from whoever they can get it when they can for free. ( Dare I call them opportunist) They are bent that way and don’t see the value in an ounce of prevention beats a pound of cure. Then there are those that appreciate people above things, like yourself, and try to help people by anticipating their needs as to be of your best and most authentic in your pursuit to help them. You are proof that honest people still exist in the world! You are just wired that way, plus you’re not the type to give up easily and is always willing to learn and tap into your potential! Thank you my friend; Don’t change a thing!

[@habatroll4831]

I feel your pain. That is a tough situation to be in. I hate when a customer asks for the worst case dollar figure. That is why we charge a diag fee. My takeaway: Don't give a worst case solution over the phone. Always verify the concern and gather some data before drawing any conclusions. A diag fee is worth the expense especially in these situations. Excellent information. Thanks for the vid.

[@SAAutoRepair]

Hey Gary. I have no issues with charging a diag fee and neither does the customer. This was one of those situations where the customer happened to be here with another vehicle and asked "since I'm here" kind of things. He totally understood that it needed to be properly diagnosed. He was extremely cash poor and truck was in another state. So he decided to wait. Hence the snowball effect. Thanks for the positive feedback sir.

[@faustogonzalez8397]

Great video, 1st as in any Automotive repair procedure you have to understand the complete components of the system and how they operate, as well as how they are controlled. That P1445 code should have alerted you of a Bank 2 (vacuum controlled check valve #2) was not operating correctly. And as you determined the SAI Solenoid that controls the # 2 check valve was malfunctioning. Next, you could have put a hand held vacuum gauge on the output of the #2 Solenoid that feeds vacuum to the #2 check valve and you would have determined that there was no vacuum being routed to the #2 check valve. You could also use a Bidirectional Scanner that can take control of the SAI and activate it and monitor via the Air Pressure sensor in the Diverter valve, whether when the Air Pump is activated by the Scanner it monitors the pressure drop while both check valves are closed and then activates each check valve individually and monitors the air pressure to confirm overall air pump Operation (GOOD OR BAD) and also the Check valves whether they are good or bad. As far as Limp Mode/Safe Mode I don't know why that was designed to be activated when SAI codes are generated, so if there's multiple SAI codes generated, you're somewhat stranded on the Highway, like if you're on a long trip ??? Man that stinks, for goodness sakes the main purpose of this SAI system is to feed clean air to the cats on cold startups, to minimize the time required for Cats to reach efficient operating temperatures, therefore minimizing pollutants on startup ??

[@martinguitarhd28]

Wow what a nightmare of a job.Nice walk through on how you handled it.

[@SAAutoRepair]

Thanks so much

[@Jpilgrim30]

Horrible design on the Air injection on these vehicles. Not only is it prone to failure but it’s buried under the intake. Then on top of that they put the vehicle in limp mode. Some of these vehicles will drive the best of us nuts 😂

[@SAAutoRepair]

Over engineered as well. Thanks for checking in.

[@ScienceOfDiagnostics]

Great job Corey. I've been looking forward to this video and I second PJ. Best way you could have handled this vehicle.

[@SAAutoRepair]

Thanks Chris. This vehicle spent too much time in my vocabulary

[@SmittySmithsonite]

What a friggin nightmare! I'd have probably gone the exact same route you went, only I would have swore loudly, and often, while doing so. 😁 Nice work getting that nightmare out the door, Corey! 👍🍻

[@SAAutoRepair]

Oh, don't you worry. There was plenty of swearing. Thanks bud

[@SmittySmithsonite]

@@SAAutoRepair - Hahaha, I can imagine!

[@bartscave]

So maybe his original self diagnosed “ slipping transmission “ complaint was actually this limp home mode?

[@SAAutoRepair]

Extremely possible and likely

[@CubasAutomotive]

That was my thought Bart. Then Everything thing else was made worse by it sitting. Lol

[@NormWilkins1]

Although it was a wild goose chase you found it. Good job!

[@nicknicu1787]

I might be too dumb to understand why Toyota’s strategy is to put you in “ Limp mode “ during the 3rd trip monitor,but I’m thinking for emission purposes to force you to fix it... If you just have the CEL on you might continue driving,if you’re in “ Limp mode “ then it’s a different story. Because secondary injection system should have nothing to do with drivability!

[@SAAutoRepair]

I believe it's because if the valves are stuck open, exhaust gas is being pumped back into the engine compartment. From there it may find a way to the passenger compartment. Then follows the lawsuits. Thanks for the great question.

[@arthurfricchione8119]

Corey, sometimes it doesn't pay to get up. Just lay there and hope it all goes away. It never does. For your sake, I hope it doesn't come back. Good luck and don't answer your phone. Just park it on the Belt Pkwy overnight and I guarantee you your problem will be gone. Have a good one Corey. Artie 👍👍👍

[@SAAutoRepair]

I don't sweat it Artie. It's just a machine. It won't win. I still love what I do and will always answer the phone. In fact, I'm the one that usually makes the follow up phone call a week later to make sure all is well and the customer is happy. Hope you are well my friend. Thanks for all your support

[@gangfer]

I know this was post awhile back. Im getting p1445 after replacing the two new valves at the back. All the the vaccum lines are good. I can hear the pump works but still getting code

[@chitoa6227]

P2445 is killing me at the moment, I felt your frustration

[@1juan0723]

did you fix your p2445?

[@robinacosta530]

Currently struggling with the P2445 code. Has anyone found the fix? I’ve added a new air pump and an air injection control driver. Mechanic states the 2 valves in the back open as needed, fuse isn’t blown and air is going through the vacuum valve as it should. But check engine light won’t go away. Pump works for a bit then quickly shuts off and triggers a check engine light. Anyone found a solution?

[@tommymarkham4202]

That’s a tough one. I’ve been in situations like that a couple of times over the years and it sucks. And the design on the SAI one these things are terrible. I’d like a sticker, I’ll hit you up on FB, lol.

[@SAAutoRepair]

Hey Tommy. Yeah, it sucks when it happens. Some good explanation, an understanding customer make it easier to get the job done though. Shoot me an address for the sticker.

[@kevinbarry71]

Love the information, however, when Toyota tells you to replace everything, it's probably best to just do that

[@SAAutoRepair]

I hear ya Kevin. Too many times, the "replace everything" is just a cop out on their part. Thanks so much for the support

[@scuba422123]

wow cory! I guess your procedure was a hair transplant with mr bosley I could use that myself...I would think the manual valve would move with the tight cable...and do a shift... and what a mess with that air injection system and the limp mode!!! I hope not to get something like this but I learned something here when this crap knocks at my door the bottom line its fixed...blood pressure down !!

[@SAAutoRepair]

That's my goal after all, to share and learn from our experiences. Hope you are well

[@PaulyD0859]

WWSKD (What would Scotty Kilmer do?) He’d tell the owner to get a cheap code reader and clear the codes before each trip because Toyotas are the best cars ever! Nice job! That’s the kind of diligence that actually gets cars fixed right. Even though you replaced a lot of parts, it wasn’t parts cannon gunnery because everything you replaced needed to be replaced. You can sleep at night because you know you did the job correctly and didn’t waste the customers money. Hope you’re feeling better!

[@SAAutoRepair]

Wwskd! That's hysterical. Appreciate the positive feedback sir

[@PaulyD0859]

S & A Auto Repair, you’re welcome. I’m pretty stingy with positive comments. Only those who deserve it get them. You earned it, keep up the good work!

@@PaulyD0859 much respect. Cheers

That is one nightmare scenario. The 3 strikes was unexpected. Made the best of a very bad hand. Hope your health is ok.

[@SAAutoRepair]

All worked out well. Health is fine. Thanks pal

[@thebaldmechanichardatheari1124]

Rock or hard place. If you just had a crystal ball. It is tough but a person always learns from mistakes. It just seemed that every time you turned around something was working against you!!!

[@SAAutoRepair]

And way too many phone calls to the customer. Thanks goodness he's a great guy and very understanding. He also knew I would never BS him.

[@wyattoneable]

Along this troubleshooting debacle you must of come to the point of where you think "I have to call Keith". What a pain. But sometimes you just have to take on the challenge and besides, we have to know what's going on because we're professionals or really stubborn.

[@SAAutoRepair]

Keith stopped by early on. He did a reset and thought it was good. I think he was surprised by the limp mode debacle as well. And yes, we are professionals AND we are stubborn. Cheers pal

[@High_Tech_Mountain]

Great video Corey. Talk about a series of events! It never had reduce power message or anything correct? It just felt like it was in limp mode and made you look at the criteria? I’ve never seen a list for limp mode setting codes. Guess I never looked it up. Great walkthrough. Thanks for sharing wit us

[@SAAutoRepair]

No light or msg. Had me chasing my tail for a bit. To be honest, it was the first time I've seen limp mode codes laid out like that. Thanks bud

[@billmck12345]

sounds like you are at joe's shop...ha ha ha... I hear ya! .. same thing with a tow in for no start or barely running and unable to test drive....the only thing is consult costomer and inform that vehicle needs to be running and survive a road test and go from there

[@SAAutoRepair]

Joe's not far away. We run into a lot of the same stuff. Good to see you my friend

[@martinlavoie4002]

Happened to my Co worker and close friend we ended changing the pump and the valves and bingo it fixed it. And the symptoms are exactly like you described. And I bought the kit from Toyota cause like you I had been bit by this problem. My advice is to always research the google and see if there is common problem with you’re code. The sad thing is that you got no chance test drive the vehicle so you got sent the wrong way. The error is human we have all had problems where the customer sends you up the wrong path and there is now way to verify. I don’t think you did anything wrong with rebuilding the transmission although Toy transmissions in my opinion are pretty rock solid. Just sucks that this customer now thinks you are not a competent mechanic but hopefully he is an understanding person and can see the situation of having the vehicle not drivable made it hard to get to the root of the real problem. I am sure he will need brake rotors if the shifter cable and linkage got all rusty those rotors must have imprint of the pad on them another expense. All I can say for advise is to use the Google and research everything if in doubt. I replaced the whole kit being in the North Canada salt belt cause I got burned like you trying to save the customer money then getting bit with the customer not being happy more money has to get dropped into the same system you were working on. Then they talk bad about you and you know as well as everyone it takes seconds to loose business but takes years to get business. So this time when the co worker came to me with inj pump faults on his Toy Tacoma I just gave it to him and let him know the manufacturer recommends replacing all components it’s not cheap but I had been bitten before and that I could just do what was wrong but it could come back to get him. He agreed to changing everything. Of course I had not sold him on a transmission rebuild as in you’re case. Anyhow keep up never give up and love the videos and how you reply to most you’re comments. Feel like a brotherhood with you

[@SAAutoRepair]

Customer is good with me and my work, so no worries there. He is very happy it got sorted and understands the "snowball" effect that was created by parking it for so long. I agree the issue may not have initially been the trans but the rebuild became necessary and justified. Just stinks it could have been avoided. I don't rely on Google as it tends to provide a lot of misleading info. That's not to say I don't get my fair share of bad info on the subscription based services I have access to. In the end, it's all good. Appreciate your kind words and support. Cheers and stay warm up there.

[@kennypatrol2zero616]

You Need a wee Dram (whiskey) after listening to the full video, lets say the trans, was faulty, BUT, letting it sit for 6 months? all the components could have seized up, solenoid's diverter valves, I don't see how you can cut yourself up about it, but you fixed it, NOW have another wee Dram, cheers, all the best

[@SAAutoRepair]

Thanks pal. I may take you up on the whiskey suggestion. Cheers

[@shaunsautorepairs5410]

I dont think you could have done anything diffrent.. It does make you think though.. Ive had a few jobs ive diagnosed and they say "great ill bring it in next week" .. Several months later you realise you havent seen them so what happened.? Are they still using it as is or did they use your diag to get it fixed elsewhere...who knows... Keep up the good work.

[@SAAutoRepair]

You're right. It's impossible to keep track of all diag and conversations. Appreciate the support

[@moody2812]

thank you

[@CubasAutomotive]

Ahhh... the problem child... or one of them. Lol. Just starting this vid! 😍

[@CubasAutomotive]

Lol... yeah, I remember that wrong service info! Just wow... Originally, I think the customer misinterpreted the "limp mode" for a trans issue. When it was probably that Air diverter being the issue. Then it was the customer who let the car sit which made it all worse. You definitely handled it the best you could with what you had each time you dove into an issue. Lol. No negative comments here. I really enjoyed this one Corey 😊 Hope you're feeling better too!

[@SAAutoRepair]

Thanks Cuba. Yeah, I'm good. Just some 50 yr old check up stuff. You are correct in the timeline of faults. It's all ironed out and everyone is happy.

[@Joetechlincolns]

Good ole Toyota couldn't add a Limp in light like Ford's Wrench/ETB light? Good grief. Lol

[@Joetechlincolns]

Glad you figured it out, sorry you went thru all of that.

[@SAAutoRepair]

I'd even be ok without the limp light if they just correctly identified the codes and system that would cause it. Appreciate the positive reinforcement sir

[@geoffrwelsh]

Lesson is.... when Toyota says "replace everything" you just do it or junk the truck. :-)

[@SAAutoRepair]

Yeah, I just have a hard time with the "launch parts at it" even if it is from the manufacturer

[@russelllacy6950]

why didn't you scan for codes in the beginning?

[@SAAutoRepair]

If you remember in the beginning, the car didnt run. Grabbing at a code without being able to troubleshoot wouldnt have gotten us anywhere. Trans, cable and detent switch just to get it running and driveable. Hope that makes sense. Thanks

Can’t you just bypass the SIS? There are some fairly inexpensive kits available as seen on KZbin.
