[s-cars] coolant temp warning

[Bill Clancy]

Lately I get that coolant temp warning indicator in the center of the dash -- the one that flashes with an audible tone.    Has anyone had that problem?     The coolant temp gauge can be cold or normal when this happens -- and usually when the engine has only been running for a few minutes.    And it almost always alerts me just as I am accelerating.    

At first I thought the thermostat was stuck, but the I get this warning when the engine is still cold (at least I think it is cold??).    

Is there a sensor or sensor connector somewhere that can trigger this warning if defective?     

thanks,
