Check engine light on and "VSC off" light blinking with the ETS light on.

I have a 2009 Toyota Corolla S, a couple years ago, I was driving on the highway and the Engine light came on with the VSC light blinking + Trac light on steady, and i felt some drag in the acceleration. I was about to bring it in to my service shop, but I googled what could be the problem. I read mentions of the gas cap. Ok, here it is. FIX: I pulled off the highway, parked, turned engine off, took gas cap off, put it right back on, went in car, now before you start engine, step on the brake pedal holding it down, now press the odometer button holding it down with the brake pedal together, now put key in ignition, turn to the ON position and then turn your engine on. All my lights went out, RESET accomplished. / It just recently happened again after I stopped at a gas station I never went to. So I ran through the same steps I just explained and it worked again. - It seems that some service gas guys dont tighten the cap enough, and the pressure in the tank is released which sets off the warning lights. The cap should be on tight and most caps get only the 1 click turn that means it is tight.

Really, you need to scan the car for codes, as there are several hundred. The VCS and ETS are all part of the same system, that being the power train control. Since you have an ETS light which is a malfunction with the electronic throttle control, then you will get a check engine and a VSC light as well as they are all dependent on a properly working electronic throttle system. Again, get all the real codes, not a parts store quickie scan and then deal with the problem. Remember, Toyota has had problems with their throttle systems, I have never seen an accidental, unwanted acceleration, but I have seen pedal and throttle position sensor codes several times with theses systems.

Get your car to a Toyota dealer and ask them to repair it. It should be covered under warranty. Without proper diagnostic no one can really help you since those lights could be on for hundreds of different reasons. Yes, one could be an ABS wheel speed sensor. Zee

take it to the dealer

My passenger compartment was wet when running the air conditioner. Then my dash lights came on flashing and the check engine light . Cleared the condensation line on the passengers side behind the carpet. It was plugged and gushed water until I blew out the lower line. I removed the negative battery terminal for 30 seconds and all the dash lights went back to normal.

Having same problem and I noticed the a/c was on Instead of the back window defrosted.as a woman I'm confused what u mean and exactly where the line is.im confused on u saying passenger side behind carpet....clziegler96@gmail.com thank u I take negative cable off count to 10 put cable back on and lights off. I heard it's a senor and one said gas cap one saids lines under passager seat.it should be a recall.toysto should stand up to there responsibly. One day I'll take it in but I still take negative cable off and still drives after 10 seconds and put cable back on.

The Intake Air Temperature Sensor is what I got same thing happened unplug intake mass air flow sensor and blow it through clean it. Then take out air filter clean it out as well. After put it all back and turn the ignition on not the car just ignition 3 times on and off should make it disappear same thing happened to me just 15 minutes ago on my 2012 corolla sport.

It's a sensor in the 2010 Toyota corolla I just had mine checked

Flashing VSC off light and engine light came on. took it to the garage. they said it was the O2 sensor, that light comes on . You have to have it diagnosed. there are way too many varibles, you will never guess it

Thank you so much I followed your steps exactly and just like magic my car is working like new again. You are a genius my man I first I thought you were pulling my leg but I tried it anyway I pulled out the gas cap put it back on stepped on the brake held it for a few seconds pushed in the odometer held that for a few seconds turn the car to the on position waited a couple seconds and then I started the car. Work like a charm I will recommend this to all my friends who have the same problem.
