It has been doing it for over a year or so. It is completely random. I can
drive it all around the neighborhood on short trips and never see it. I
know that there is coolant in both the radiator and overflow tank so I just
kind of ignored it. I have had the cooling system flushed after it started
thinking that maybe it would clean up the sensor or something, but that
It usually seems to manifest itself after a highway drive for over an hour
or so when the engine is nice and warm.
Does the sensor possibly need to be changed?
Thanks for the reply.
