That is normal. I'm sure up where you live is colder than Texas so yes it may take a bit longer for your light to go off. Only real way to tell is to hook up a OBD2 gauge and monitor it.Exactly and thank you. When I first acquired the vehicle the idiot temp is lit on. But recently this week when I start the car the idiot light takes 30 to 45 secs to go off. I called Toyota they said that is normal but I'm still skeptical about it. A buddy of mine drives a 2nd gen told me his idiot temp went off after 30 secs on start up.
