Hello , im a newbie to your forum. I have a 2001 4wd 4runner limited I"m having a problem , every morning if the outside temp is 30 or below my brake light and my ABS light and warning signal comes on and they stay on until the under hood temp get good and warm , My question is , is there a sensor under the hood that would cause this? If so what do i do to stop it ? it drives me nuts
