Question about Ford Cars & Trucks
The code means that the ECM detects that the engine coolant is not getting hot enough, fast enough.
There are two reasons this code can set. First, and most common, is a defective thermostat which is stuck open or opening too soon.
The second is the coolant sensor itself or its associated wiring could be faulty.
The car is 11 model years old. If you have never changed the thermostat, now is the time. If that fails, then try to replace the sensor. Both are usually located in the same general area, since the coolant temperature must be monitored near the thermostat for the most accurate results.

Testimonial: "so if the coolant is full and I have heat and my temp gauge is normal you still recommend changing the thermostat before the sensor"
