Yes, mine'* faulty, too. I thought maybe the bad chemistry of my really old coolant was triggering it. Last fall I did a complete flush-and-fill (even added the Prestone flushing tee in the heater hose, and boy was _that_ a pain to install), got the mixture of the new stuff just right, but the sensor'* still complaining.
It'* plugged in on the passenger'* side of the radiator, about 1/3rd of the way down. Look straight down the back side of the radiator directly below the radiator cap. You'll find a two-wire electrical connector plugged into a square-ish plastic thingy. Unplug the connector and the warning will shut up. I forget how the sensor itself removes (it'* real easy -- it more-or-less just plugs into a hole), but of course the coolant comes gushing out when you do that, so don't pull the old sensor out until you have a replacement ready to go in.
Speaking of which, can anyone provide a part number and price?
