Default GX 470 Warning Lights VSC OFF, VSC TRAC, Anti Skid, Check Engine

I just bought a used 2007 GX 470. Checked out fine and was great for 150 miles. Very cold day today and the Warning Lights VSC OFF, VSC TRAC, Anti Skid, Check Engine all came on.

I read a thread about O2 sensors and the gas cap.

Any thoughts? Car seems to run fine.

Mine went on after a light impact in the rear.

Was on for a few days and went off.

After research and talking to Lexus service department it can be anything from loose gas cap, sensors (oxygen, etc) low brake fluid, and many ore things.

Might want to run it by someplace and have the code checked out.

Default Thanks

I am going down to Autozone today.

I may bring it to a dealer just to be safe. How long before it damages something more if it is an O2 sensor?

It could be anything, just get your codes read and tell us what they say.

OK. The codes were all evaporative emission codes. 441, 455, 456.

I went to a friend who is the service manager at a Cadillac store. He plugged in, checked then cleared the codes and said it was most likely the gas cap, which was loose.

I bought a cap from Toyota for $23. So far, codes have not come back, but I only drove 20 miles.
