Engine "check" Lit Options

[Corolla04]

Hi there from Columnbus, Ohio,

I just have a porblem for my corolla 04 LE that the engine lit on two weeks ago. I had already checked with the gas cap and everythig seemed fine. After a few days later, the engine "Check" lit was off. However, the engine lit is on again today. I have no idea what is going on but it gives me a feeling that the engine "check" lit will be on when the temperature is low about 10F to 20F. Will anyone have such scenario before? Any suggestion?

Thanks,

kip
