VSC, TRACOFF, Check Engine lights, are on, I really don't think you guys/gals have anything seriously to worry about. These 3 codes have been coming on intermittently since I bought this car, I never really paid too much attention to it, I have driven from FL to Texas at least over 10 times with these lights fully lit, now mind you I do regular maintenance on my vehicle religiously, from the serpentine belt to the transmission oil, to regular oil changes(synthetic). My point is these lights have come on they go away and I yes I have replaced the gas caps, reset my battery and the codes go away and come back another day, but my Lex just keeps on keeping on...

Jess here, I have a 2005 ES330 Lex, and I really don't think there is anything to worry about with the check engine, trac off, and vsc light on. I have had these lights on intermittently for the last 3 years, I have driven from Fl to Texas and vice versa for at least 10 years with these 3 lights on and never have had the slightest of problems. However, with that being said, I do keep up with maintenance like oil changes, transmission fluid changes, and serpentine replacement, and have my coolant checked regularly.

I have a Highlander 2005 with the same problem: the VSC, check engine, Trac off light on in a the past few weeks , then it was off, and now it came back the light on.
I bought a gas cap replaced it yesterday, running for about 50 miles this morning the light still remain.
Did anybody has this same problem ? how can we fix by our own ? Thanks

I had the same lights come on after filling up at a particular gas station (during a state fuel shortage, must have gotten debris from the bottom of their supply tank). Had the lights for the longest time. Then I changed my oxygen sensor, replaced some hoses, and adjusted the timing belt. Haven't had the lights come on for quite some time now.
