I replaced the gas cap and the problem went away for about a year. It came back and instead of buying an Autozone gas cap I bought a genuine Toyota gas cap. It was not too expensive. Only $22. I have found some after market parts superior to OEM Toyota but this is one that is superior to after market. Light went off and has stayed off.

Toyotas are horrible cars, they have a lot of engine n electrical problems Nissans are far superior cars

The vsc trac and check engine lights are on. This has happened 3 times (at least) in the 1 1/2 years I have this used vehicle. Very frustrating

My 2004 Sequois has the VSC and engine lights on. They need to fix it at no cost.. it is pain, and I do not know if is ok to drive without fixing it..
