temp gauge stays on cold on 1997 Ford Windstar

My temp gauge stays on cold all the time. I do have coolant and the heater works but the van does not overheat. Could it be a sensor. My check engine light is on.

your thermostat is stuck open and needs to be replaced. the code is probably for the engine not reaching normal operating temperature. Roy
