Hey. Late I know, but I have this code too. I'm pretty confident it's the thermostat not closing correctly, and confusing the thermister. I know my thermostat sometimes sticks open, but it seems the failure of it to close again when the temperature drops triggers the light. Eg I parked the car for thirty mins, stat stuck open, engine was stone cold when I came back, EMS light was on.
I don't get any other codes like you though, and my fan is not running when cold.
I will change my stat on the weekend to see what happens. Did you get any further with yours on the past four weeks?
