Very good information!! I have the same lights coming on, will check all the ones that you pointed out. Thanks again for your knowledge!!
I have same issues on recently purchased 1st gen. I will follow your example. Thank you for sharing and God-Bless...subbed
Thank you very much , you explain these steps to fix my issues with my Toyota Sequoia.. straight to the point.. I’ve Subscribed to your channel.. Thank you and I’m glad I ran across your channel.. God bless you for saving us all allot of $$$$$…🙏
Happy to help!!
2006 Sequoia, I had VSC,TRAC OFF,ABS Brake light on, truck felt like it wouldn't crawl more than 15 mph...Literally felt like it would fall apart. I had many error codes. Changed ABS wheel speed sensors and the VCS TRAC OFF & ABS all went away. For the brake light I replaced the stoplight switch located under brake pedal and it took the brake light off. MAKE SURE YOU USE A SCAN TOOL. Video on my channel
What’s your channel?

@@castlecruuz thanks for your vid, man. I subscribed
@@CPT891 You're very welcome brother
I really appreciate you subscribing to me man
Great video. Good practical techniques and troubleshooting.
Thanks! I'm going to be posting a follow up video with more info, as it turns out this VSC thing is a DEEP rabbit hole.
Pablo ur great thanks... I have the very same issue (just purchase it) 2003 sequoia 2w...I'm shipping the car to Costa Rica
Thanks
Pablo Torrentez
Thanks for the knowledge
Thanks your video is very helpful brother.
Hey Brandon, I owned a yellow 1990 vw corrado G60 from 1990 to 1999. Loved it
Definitely appreciated my G60 for the 16 years I had it, but no lie I am enjoying the VR6 so much more ... probably because I'm not worried about a grenade going off under my hood every time I drive it :)
@@CliffjumperCars That was the first VW V6 engine. This 2007 Rav4 v6 is my first v6 vehicle and I love it.
Great tutorial! Thanks.
Happy to help!
What a god send
Excellent info 😊
Happy to be helpful. Got a follow up video coming up soon on this issue, as we discovered more problems that can contribute to these lights coming on.
Best mechanic
A great video from a brother in Christ thank you for your help God Bless! 🙏🏾
Happy to help!
Link or name of the 3 sensors. Thank you!
Thank you 🙏
Happy to help!
I had the same problem / our Left Rear tire blew and twisted up the vehicle metal and was having big issues with this vacuum leaks and my friend who has a body shop redid the whole rear vacune and hoses issue..
just bought me one a second gen but i don’t have the VSC off light on but the one under the VSC TRAC light. it’s the one with vehicle with the tracks (wiggly lines) im trying to remember the name 😅 traction control!
Some people say it’s the yaw rate sensor. Some says it’s the wheel speed sensor. I will definitely try this diagnosis this summer. Do you know how much those valves are? Thanks so much for video!
It turns out that the combo of these generic OBD codes and these malfunction indicator lights on the dash can actually refer to quite a number of issues. The factory level diagnostics scanner can reveal the specific issue, including the yaw rate sensor, an ABS sensor, any of the four O2 sensors, evap valves, etc.
Thanks kindly
Excellently done video, sir. You have a real gift of talk (not sure I heard even one "y'know")
Now, do you have any clue what might cause those three lights on my '03 Sequoia (CEL, the two VSC lights) to all come on and all go off intermittently? They'll come on and stay lit for a day or two or three, then they will all go off and stay off for a day or two or three. And then the whole cycle repeats itself, over and over and over. Meanwhile, the car runs just fine.
I've replaced both O2 sensors, the gas cap, and the spark plugs. No change. Could it be a vacuum leak that comes and goes? Could it be the catalytic converter?
I probably need to do a follow up video to this, because I've learned a lot more about these lights, what triggers them, and what they can indicate. To simplify though: VSC and TRAC lights will always come on when the CEL comes on. There may not be anything wrong with the VSC system, but they will always come on when there is a check engine light. I guess it's Toyota's way of really drawing your attention to the CEL.
HOWEVER if the VSC and TRAC lights come on and there is NOT a CEL, then that indicates a different problem, which could be the actual VSC system, it could be the ABS system (ABS light does not always come on even if it's an ABS issue), 4WD system or center differential. It can also have to do with the Yaw sensor, or the steering angle sensor. It seems that performing a zero point calibration often fixes this condition. But sometimes you need to replace the yaw rate sensor then do the zero point calibration again.
Also, the VSC light can come on with just the Brake warning light, or with the ABS light and the brake warning light. Those indicate issues specifically with the ABS system, which can be a failure in the control unit, a corroded connection, a dirty ABS sensor, a broken ABS sensor... a few things.
Whatever is specifically wrong and causing these lights in whatever combination they are popping up can't be determined by a generic OBD code reader, but if you use an enhanced code scanner then it will give you the specifics, so you're not guessing.
Sounds more like a Vacuum leak ? Or possible? One of those Vacuum valves getting stuck open? Test the valves first and check for leaks.
WHERE did you get your smoke unit from? and also the valves

...had to do the SAME THING to get my spare tire off.. 6:45
uuugh. I guess it's good motivation to occasionally lower it, clean & lube it, so it keeps working & doesn't get frozen when you need it to work.
Whats the name of that part
Mine doesn’t have the check engine light and it turns on when I be braking once it turns on it doesn’t turn off
My L light comes on and off while driving... How can I fix
Hello from POLSON, MONTANA! I am a brother in Christ, (Catholic) and thank you for your video, and for your PRAYERS! We (my fiance, Gretchen and I) get married in October, and could sure use prayers-- about a living situation and just for general health and happiness.
Now on to the car:
I JUST purchased a 2005 Toyota 4Runner (4.7L dual overhead cam V8) and all of a sudden the Check Engine, VSC OFF and VSC Track as well as Traction Conteol (the slippery car symbol) came on at the SAME time (after the car sat for a day and a half)
Any further knowledge about this issue? I cleaned and checked (clicked) the gas cap, and filled the tank, but haven't had a chance to check any codes yet.
Welcome to the fun! The good thing to know about these three lights coming on is, whenever the CEL comes on, the VSC and TRAC lights also come on. The bad news is: when that Check Engine Light comes on, it can be just about anything. There are dozens of codes that can trigger the light. Would be irresponsible to speculate without knowing the codes. Also worth noting: a generic code reader will most likely NOT give you all the info you need to diagnose the problem, as Toyota as their own specific codes that need to be read from their manufacturer specific computer. Best to take it to a shop that focuses on Toyota to get it scanned. The regular Autozone/Oriellys/Pep Boys scan will not help you.
My truck is running lean, and you can smell the gas real bad, and it also has a lot of pressure when I open the tank cap, whats wrong do you know?
Sounds like a purge valve is not functioning correctly. You'd need to spend a bit of time with a power probe, do a smoke test, and see which valve isn't working.
have 02 Seq same extreme gas pressure and smell random shut offs. someone said vent vale solenoid but can't locate
Will my traction control still work even though the lights are on?
Yes - the VSC and TRAC lights always come on whenever the CEL comes on, but it doesn't mean the traction control is off.
If the VSC and TRAC lights come on but there's no CEL, then then traction control does have an issue. Usually the brake warning light is on also in that case.
Can a bad gas cap be the problem also?
Absolutely. That can cause it, in addition to a leaking charcoal canister, a bad purge valve, a leaking vacuum hose, bad or loose O2 sensors, LOTS of possible causes.
Gut
wrenching
I have spent $1,200 so far and each time I pick up my Toyota from the mechanic the lights stay off for around 15 miles. Then they come back. Don't know what to do from here. I need cruise control. I just put on a new gas cap because I heard it could cause the problem. Didn't help.
It's a frustrating issue for sure. What I found was that scanning with a regular scan tool didn't lead me to the actual problems, as it only identified generic OBD codes that could each have many causes. Scanning with a Toyota specific tool to get the factory diagnostic codes was the only way to nail it down. Even then... it's a 20 year old platform with a lot of parts that go bad from age, corrosion, vibration, wear & tear. Repairs are going to be more and more common the older they get.
Mines are on but now my power steering wheel went out 😮2002 Toyota Sequoia limited 😮
Boooo! Sorry to hear about that. Power steering is mechanical and the error codes are not related to that. Just an unfortunate thing that in old vehicles like ours, multiple things are often wearing out at the same time. :(
Do you fix Sequoias?
Occasionally I have to fix mine :) Other than that, I'm a shadetree mechanic. Used to run a referral only performance shop, but I pretty much stick to my own car projects these days.
Did you ever get this resolved. I’m having the same problem. Mechanics are telling me different things
You never show if the ligths whe off asi have tha problem
Great video if you don’t mind listening to all the jibberish
VSC OFF /BREAKS lights on But no CEL
That means there's a problem with the ABS, brake system or traction control.
Gas cap or abs sensor
Those would certainly be “usual suspects” but not the cause in this case.
We also ruled out the carbon canister, several purge valves, ABS computer, steering angle sensor, & yaw sensor.
@@CliffjumperCars so are you saying you still haven’t figured it out?
@@sebastianromero420 We did, and it was a combination of things that aren't in the usual diagnostic process. Will cover it in an upcoming video, but here were the biggies: 1) one of the new purge valves failed *intermittently* - could only catch it with a scanner actively monitoring while the motor was running. It tested fine when the ignition was off and tested fine on a multimeter. 2) the OBD port connector itself had several issues - several of the wires going to it had faults and it needed to be repinned and the wires repaired.
I did everything you did in both of your videos, but the light still comes on, so what do I do next?
I've got a follow up video on this that will go live tomorrow at 5pm... found some more related issues that may apply to your situation.
@@CliffjumperCars thank you so much and God bless you and your family 👍
@@CliffjumperCars I forgot to tell you the lights stayed on right but when I started up in the morning, the lights ain’t on until the car warms up so I don’t know what’s causing it or why some say you can reset it so many different problems that can cause the lights to come on and my engine light don’t even come on over is burnt out or not so I’ll wait for your video then. Thank you for your time. God bless. PS if I don’t get this fixed, I won’t be able to get it smog will I ?
