Today we continue diagnosing the CEL, VSC OFF and VSC TRAC lights on the 1st gen Toyota Sequoia... what could possibly go wrong?
Using a smoke tester & multimeter we will delve into one of the more annoying and increasingly more common problems on this aging platform.

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

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?

@CliffjumperCars Жыл бұрын

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.

@robertbenavidez7164 6 ай бұрын

Sounds more like a Vacuum leak ? Or possible? One of those Vacuum valves getting stuck open? Test the valves first and check for leaks.

@manuelantolin3116 2 жыл бұрын

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!

@CliffjumperCars 2 жыл бұрын

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.

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.

@CliffjumperCars Жыл бұрын

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.

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.

Will my traction control still work even though the lights are on?

@CliffjumperCars Жыл бұрын

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.

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.

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.

@CliffjumperCars 3 ай бұрын

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.

@@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.
