You would of made a excellent old school teacher. I say old school because they would of came up with their own curriculum and not just be a programmed robot playing a recording. It's rare to be knowledgeable about a subject and to be able to teach it. The old saying people in the top of their profession practice that profesion, and the people who can't compete teach..

Thank you for this. HELPED DIAGNOSE my problem with my Sienna.

This video 📹 is GREAT!! THANK YOU!! GREAT EXPLANATIONS!! Very DETAILED. VERY thorough!! Going to try ALL these things, although-- from the video--I suspect it is the PURGE VALVE. 🛠

I think you covered all the possible causes...great job, sir

I'm a retired mechanic, and this morning when I started my 2005 Toyota I saw the VSC TRAC and Check Eng lite on. I didn't have time to check it, but later on I was checking Google as to what the VSC system involves, and came across your video. I never thought that a emission failure would cause the VSC light to also come on. At this point I'm guessing the attendant at the gas station left the cap loose yesterday. Hopefully this is the problem, I'll check it when I get back to the car. Great video.👍

Thank you for saving me a whole lot of fixing.

Great informative video; you cover every base; which most videos don't !!!!!!! 👍👍👍

I have a 2005 Lexus RX330. I just had added per Lexus owner's manual dexron III AT fluid to power steering reservoir and the vsc and trac off lights plus a flashing check engine light and rough idle and rough as I drove back home approximately 4 miles. Plus the weather the past 48 hours has been raining with foggy conditions and temps of 40s F - 60 F. And only have approximately 3 gallons of fuel in tank. Thank you in advance for your help and great videos.

Thanks and your diagram was quite helpful.

Nice job partner! Really helpful!

Thank you for suggesting this video. I commented on another video of yours. I think it might be the Wheel Speed Sensor that's causing the VSC lights to turn ON. I took my car to Pep Boys, a US Franchise Service Center, to replace the Starter. I noticed upon picking my car up, they handed me my wheel lock, so I knew they had to remove the front wheels to replace the Starter. Prior to taking it to Pep Boys, the VSC never came ON. I am taking my car back to Pep Boys tomorrow and have them check the Wheel Speed Sensor. I don't want to spend anymore money on this car. It's 16 yrs old and I am trading it in for a new Toyota Camry. As for the O2 Sensor, I don't see any black smoke. I did test the fuel cap as you suggested in the other video and that didn't work for me.

Thank you. You are one of the best.

Thank you sir. Very good information and demonstration. 😊

this video is Great what is the name of that diagonis machine

Have an ‘08 Sienna XLE. had all these random misfire codes (VSC) and even would have to shut my van down as the “traction control” light would blink along with the engine light causing the van to lose power and decrease in speed, till I shut it off and restarted it. And that would take care of it for a week or so then back again, usually one the Highway. So off to the shoulder again as the van would slowly lose power and buck and gas be basically unresponsive Seems like maybe the compression was changing over the 200,000 miles as i started putting premium gas in and the higher octane was the key.. as all the codes went away (once cleared) and never came back. Same spark plugs. I did change one injector (before I switched to premium gas) as it did have that code come up for the number 2. But the check engine lights would still come on. But same spark plugs on all 6 cylinders as those back are just too hard to change without a good reason. Again premium gas and all my check engine lights and blinking lights are a thing of the past and it’s nice having a dash free of those. (Those lights came on probable a dozen times in the past. But now problem solved for like 9 months now and counting.

Very good reporting

You are bad to the bone,very helpful info sir

Hi thanks for your video. I recently change my sparkplugs in my Toyota Highlander 2006 V4 and 2 weeks later I got a p0456 with check engine light, trac off and VSC light. What should I do? I already replaced the gas cap and still have the code

Super educational 👍👍👍👍👍

Thanks for the info

Thank you😊

Traction control light and check engine light on after fuel pump replacement on my sienna 2016 XLE What could be the problem.

Will all three of these lights come on if someone backed into the right rear of my 2011 toyota sienna van? Soft hit, smashed in the bumper, no airbag came on.

My problem is that at the same time that light came on for the first time ever my Highlander now does a weird not exactly a shacking per day but kinda like a shack almost like a rocking feeling because of the force that's rotating in the engine or under the car somewhere if this makes any sense. I'll see what's happening

What if you've done a zero point calibration and the lights goes away for 2-3 weeks but then comes back on? Would that mean a bad steering angle sensor could be a possibility?

Hello all my wheel function lights are on Acura DMX 2007 the abs , sh-awd and vcs do you have any suggestions I’d appreciate any feedback since it’s all I can ask of. My check engine is not on though

I am gonna check my fuel cap. Clean it and receptacle as well. Turn car on. If lites still show I'll place saran wrap over the inside of fuel cap, and click it in. Turn car on. If all lites are off then new cap needed. If not will proceed with other areas in your diagram. Already spent hundreds on other stuff including 02 sensor, and I'm going kookoo.

First of all, Great video. I have 2007 Camry V6 with 100,000km. It had been no problem. But last couple weeks ago, VSC check light, tracktion light, and engine check light turned on during driving on the highway. I brought it to my mechanics, and he said nothing bad is scanned. I recently changed the engine airfilter and cabin airfilter by myself. My question is 'Do you think it might cause the problem?'.

I don’t know if this is related to your video but I have engine light, tcs light and fcws light on. I notice that every time i press hard on the brakes, tcs and fcws will light up and those will turn off only when i restart the car and don’t press on the brakes as hard as i need to. The engine light just recently turned on so i’m wondering why those two caused the engine light to turn on too.

2011 Toyota Four runner. My brakelight,VSC, 4wd lo, traccontrol is on dash. I checked battery, starter, alternator and gas cap so far.

I've just changed steering rak n i believe that is de problem of wheel allignment

I have a Toyota crown Majesta V8 model 2009, it tells to check the PCS system, one I was almost getting a head on accident yet it was on but didn't alert in anyway, how can I have it fixed, thanks.

My Toyota Aurion 2007 shows Traction control and abs light with warning light but no engine light. But if I restart the car it goes away and comes back in two days or so. One tool says no fault codes. Can you please guess what can be the issue? Thanks

I got a TRAC off and engine light on yesterday on my 2013 Corolla and the diagnostic gave me a catalytic converter or replace battery( which I replaced 6 months ago). What should I do? Thanks for the video

First I would like to thank you for your professionalism and easy way of explaining honestly it’s very hard to find someone like you I am a retired female and I can see how they lie and over charge you worst when you’re a female and much worse when you’re older . It would be nice if you put an email to be able to keep in touch Thank you so much for helping us out specially now that life has gotten so expensive and being on a pension 😢

2010 vibe, throws a c1336 code, i reset the sensor and it goes away. Soon as i start the car and put it in gear the vcs starts flashing and traction control light comes on. Gas cap has been replaced. Where should i start

I have a 2005 Toyota Sienna and all 3 dash lights turned on (Check Engine Light, VSC, TRAC OFF). Please help.

This is for folks who have time to go "back to school", sit in class, learn and then try to apply what they learned with lots of time, tools, patience. Not for everyone. I'll pay the $ and move on with my life :)

My corolla Verso Show ABS TRC and VSC off, what can I Check up?

I have a 2004 lexus es330. Whenever i wine down when driving. I do feel fuel smell. No leakage whatsoever

I have a 2012 corolla, and the Trac off/Check Engie have been going on and off (Toggles back and forth every few days). I have yet to see a VSC light go on. Could the gas cap still be the cause or would the VSC definitely be on as well if this was the cause?

I have 2007 Camry Hybrid with push button start. The car will not start. The message, "Check VSC SYSTEM", comes on when I try to start. Do I need to have the car towed to a Toyota dealer for repair? Any help will be appreciated. Thank you.

Thanks Doc, is that a fine SAFA accent I hear?

I have a 05 toyota rav4 and the code I get is p0560 . Low voltage. 😊

Mine did the same thing and it was the alternator and when the battery dropped to 9v everything lit up. I saw VSC and was like what the hell is VSC! The tow truck driver new instantly he said its your alternator. He jumped started my car and I had a meter in the trunk it was 9v with the engine running. Replaced the alternator everything is good now. You think the battery light or something would have come on before it got to 9v but nope. My car was a 2008 Lexus ES 350.

Got code p0138 o2 sensor bank1 sensor2!!! I change the sensor still getting same code!!!

My lexus is 250 has tsc and check emgine light on

I have a 2008 Lexus es 350 the issue here is check engine light & track control

Sometimes It is just a 40 amp fuse blew!

Waste of time. Doesn't tell me how to fix it

complete waist of time

The third thing you have to look at is your ……. Sensor. WHAT ? I could not understand the word before sensor.
