Thank you!! Mystery solved in my case. The check engine and trac off light came off after a few days of my wife driving my 13 Sienna. Wasn't sure why when I went to drive it myself. Later in the day I filled it up with gas and tightened the gas cap thoroughly, as i always do. Within 20 minutes of driving after getting gas, the lights went off. My wife had put gas in a week earlier.

I did 207 Thousand miles in my 97 LS400 and " never " had any lights come on " Ever " Best Car I ever owned.

2016 Toyota Corolla had the track light and the engine light on. and I had to try several times to be able to start the engine after having poured gas at the gas station. It turns out that when I checked it was the canister purge valve hose that cracked, it was broken. I changed the hose and the lights went out. and now the engine starts at once. Incredibly, with less than two dollars I solved the problem myself.

My 2016 Rav 4 has the same problem (RAC Off and Engine light at the same time). Please let me know if you have an easy fix.

Thank you

2008 Toyota sienna ce 3.5 engine light, vsc and trac off all on at same time, I've replaced both upstream 02 sensors and both lower sensor, mass af sensor, fuel cap, spark plugs, coil, and now fuel pump then cleared codes test drive and lights back on runs good though no rough running or anything . What else could it be?

Yes helps a lot because I know it’s not the gas cap

Have P0240 code with my traction control light and they recommend catalytic converter replacement. What about those chemicals you pour in gas tanks ? Any luck with them ?

If still able to help me figure out what my Toyota sienna le v6 the trac light and check engine light came on same time but when go in gear it won’t move this happened overnight take dogs to park came home next morning go to work and lights are on and won’t move changed gas cap still won’t move any idea ?

In my lc200 the check engine light came on, along with the 4low and trc light ,what could be the cause

Mine both came on at the same time says it’s my mass air flow sensor it’s brand new I tried cleaning it nothing. Disconnect the battery it went away but came back on after a few days. Not sure what else to do

Good afternoon

This video should be titled “what to do in any type of vehicle with a check engine light”

Hello what it means when the AWS, Engine check and TRAC Off lights are on at the same time?

yes hawen toyota tacoma 2013 2.7 4 cilinder po420 ban 1 stil after 4 day on now oem upste o2 sensor

I think mine is a sensor, but if I try to give it gas more than just allowing it to naturally accelerate, it will flash the check engine light, and the track light will come on however, the last time that happened to me my car was bogging, so I pulled over I stopped the car. I turned it off. I pulled the key out and then I put it back in. Turn the car back on and it was fine. This morning it happened and the track light is still on the check engine light has been on for a while now because there’s two sensors that I need and that’s like $300 for the both of them and I just don’t have it But the light did not go out so that is concerning because it is running rough And I use my car for work

My 13 highlander has these 2 lights. I changed the gas cap to an autozone one. Now its starting to do it again.

Hi, I am out of town and this has happened. Right before, there was a tire sensor warning. Air is fine after numerous checks. My question: is this 'trac off' safe to drive on until I get home?

I got rx350 2013 engine check light on and trac off at the same time , I scanned the code , it showed P219B , did any body know how to fix it what to check first thanks

Thank you!

I had the trac off and check engine light on, autozone was able to pull the code. It was P0455 and it required a gas tank cap. Replaced gas cap now, but how do it reset the dashboard warmings?

Mine just did this this am it said a catalytic converter

I have a 2020 Trd pro manual transmission. On a road trip accidentally left the keys in the on position with the engine not running overnight and drained my battery completely when I jumped the vehicle and got it going again. The battery charged up fine and is not a problem, however, I have had the same fault you were mentioning which is track off and check engine light, but also I have headlight malfunction, vehicle, stability, control, cruise control, malfunction, precollision malfunction….. and now just today I am getting spark ignition, coil, failure, primary secondary circuit

I replaced my reverse light bulb on the right rear. After doing this all the VSC, trac, 4LO, check engine lights came on. I went to dealer and they replaced the wiring harness that goes from tailgate to front of vehicle. Lights still stayed on. They then replaced the entire tail light assembly. Lights still on. Codes are C1201, P0761, P2714. 2008 toyota land cruiser. Also, my remote start will not work due to check engine light. Any suggestions?

Great Video..

I have a 2011 Toyota Camry SE not sure why but lately my check engine light blinks and my traction light comes on and car seems to bog /lag. I noticed it does that when it needs oil but I'm wondering if there's something else wrong. #neverbuyanothertoyota

What can I do to my Toyota Camry LE When my check engine light and My traction light stays on my dashboard in my car

Hi - Yesterday I filled up a gas tank and today i saw Check engine light and trac off light is on at same time on my Toyota corolla 2016 . Please help what can be the reason / causes ? Does Lucas injector clear work to turn off both the lights ? Appreciate if any one could help on this …Thank you !

Code did read gas cap. I had driven 2 miles with it off. Put it on. 160 miles LATWR on a trip and it shut off..the VSC off flashes on n off w the chk engine on ! So I got the correct gas cap and after 20 miles ITS STILL FLASHING ! So wth?

Vsc light

I went to my local autozone and it says I need a new catalytic converter

Yeah but how do you know if something is really wrong with your car?

After my lower control arms and ball joints were replaced by a non dealership, my trac off and engine light came on. Did they mess something up?

Thanks bro

Both mine came on with 420 code, catalyst system efficiency below bank 1 code, any clue to what that means? Cars still running perfectly fine, happened when I got onto a 65 mph highway in a very heavy rain.

thanks man

I think mine is yhe gas cap cuz took the gas nozzle wthh me at the station

Mine just came on while I was driving and I’m not sure I hope it’s not the catalytic converter cause I just spent 4200 on brakes and tires 🤦🏻‍♂️🤦🏻‍♂️

Autozone said its my ignition coil

Damn it I want to know how to clear it

Country where we reached moon and back but cant build decent cars

I had a spark plug on my car go bad and the engine and trac light came one.
