the CEL light and check VSC warning came on this morning. I drove it around town and it runs fine. I did some research on here and some say to retighten the gas cap. Will that instantly fix the problem if thats all it is? Or do I need to drive around for a bit? Also some say unplug the battery or reset the ECU. But isnt that method just a quick fix? I know when my VW had a CEL I could unplug the battery. The CEL would go off only to come back days later. So the actual problem isnt fixed. I dont want to do damage to my car. Anyone have experience with this?

just checked the gas cap. it definitely seemed loose so i retightened it. Started up the car and the CEL is still there. Do i need to drive around for a bit before it goes off?

I recently came across the check VSC warning too... BUT.. it was due to accidentally ripping the ABS speed sensor (i think that's what's it called) wire out of sensor itself in the front passengers location during a coilover install. Now i gotta replace it - anyone know how much a new one cost?? But been driving with the VSC warning light for the past few days with no problems.

I read somewhere else that someone had their vsc light + cel come on due to their car misfiring or an O2 sensor gone bad. Notice any diving issues or random nosies from the engine? Head up to autozone or somewhere and get them to scan it to see whats up. Goodluck

Yes, you do... or you can pull the fuse for the ECU to clear it and then see if it comes back or not. (but this'll also reset all the learning the ECU has done to this point... it'll relearn after a while but might drive a little odd initially as it'll be reset to defaults)

ok ill drive around a bit then reset the ECU if it doesnt come off.

I ran the car through the car was yesterday. Im hoping because the gas cap was lose water didnt get in there.

and this will reset my NAV data like radio presets and how I have it default to radio when the car is driving right? Im not actually wiping out NAV data like street maps and what not am I?

shouldn't have any impact on maps and such, no...you're just pulling the ECU fuse.

update:

It was the gas cap. I retightened it then called lexus service. The dealer said the car has to go threw several starts in order for the computer to reset and the code will go away. It went away after about 15 starts.
