Lately my blue light has been coming on while Im driving. My car is warmed up and I could be driving for well over a half hour. It doesnt blink real fast or anything. But It'll stay on for maybe 20 secs. or so. And it does it sporatically. Wondering if anyone else has/had this problem and what causes it? Is it a faulty sensor? Or a bigger problem??

Coolant Tempature Sensor has likely failed or is failing. If no Check Engine, expect one soon. If it's not the temp sensor (green top = old and known bad, black = new) then you may have a coolant leak, or could just be low!

Same thing happened to me during the summer. Light started flashing blue and then I got the cel. It was the temp sensor. No biggie. :)
