Toyota Repair: Abs lights, snowy weather, autoparts store

Question
My 2006 rav 6 cyl intermittently the check engine vbs and abs lights are on. Replaced o2 sensors, problem went away for awhile now has come back. I notice that it happens in rainy or snowy weather.. This has been an issue since I owned this vehicle... Thanks

Answer
The check engine light usually causes the others to turn on, I would need some diagnostic code numbers to help with this, do you have this information, if not you can have an autoparts store scan the compter ar no charge, then let me know what the codes are/
