Head temperature sensor. Either the sensor is bad or you blew a head gasket. Since you indicate that the fans run on start up it is most likely the sensor.

Fan stays on when i turn off my car,2006 ford fusion

What a pickle. How long did you give it before you disconnected the battery? You know, most fans may continue running for a short time, especially on a car that has been running at normal temperature for awhile. Reason being, the engine will actually get hotter for a bit as the coolant is no longer circulating. The fans shouldn't stay on too long. Most I have seen, less than a minute.

Be that as it may, a temporary solution to the problem, instead of disconnecting the battery to stop the fan-this is not good for the computer circuits who like steady voltage, however small-is to instead pull the fuse for the cooling fan. This is a large (80amp) maxifuse in the Battery Junction Box. The position in the box is F-29.
If it is staying on too long, the bad part appears to be a module or some type of relay-like switching device right at the fan motor itself. There are 3 wires to the fan assembly. One is the power feed from the aforementioned fuse, one is a command signal from the PCM to turn the fan on, and the last is a ground for the motor and assembly. I hope you could detach this device from the fan motor for replacement. Certainly nothing wrong with the fan motor itself. Good luck.

The cooling system may be low on fluid.
The code is for a temp sensor high voltage which could be a wiring problem or something else.
The sensor needs to be in contact with liquid coolant to work. The computer is not getting an acceptable signal from the sensor, so the check engine light is on and the fan runs for safety. The sensor for the computer is different than the one for the temp gauge.

This sounds like a bad water thermostat or a cooling fan relay stuck on Run. The thermostat should be under the top housing of the motor where the big radiator hose meets the engine.

The other method of cooling a hot motor is the electric fan attached to one side of the Radiator. This fan may run more when the A/C is on, but when you are using the heat it should not run constantly. This fan should be off when the motor is cold.

In some cases the sensor for the fan will make a trouble Code and light the "check engine" light on the dash. You can get a free scan from Autozone or Oreillys.

Once you get heat in the motor your heater should work quicker. If the motor is hot and the heater is not, feel the smaller hoses running from the motor to the Firewall. They are about 5/8 to 3/4 inch diameter hoses. They should be hot with the heater on. If they are hot, and the heater in the car is only warm or cold, you have a ductwork problem under the dash. If the hoses are not hot, you have a flow problem. With the flow problem, either the heater core is plugged or a water valve is not turning on.

I hope my solution has identified the problem and given you a way to trace it. Start with the thermostat, new gasket, and some antifreeze to replace spillage. If you did have a warning light, either disconnect the NEG battery cable for 10 minutes or ask Autozone or Oreillys to clear your car with their scanner. Old error codes will stay in memory for 25-35 Startups if you don't clear them.

What causes the fan to continue to run when controls are off?

This device is disclosed which causes a fan of a heating and/or air conditioning system to continue to run until the temperature in the duct work of the system reaches a desired temperature, so as to remove all heated and/or cooled air from the system, however, the device is designed so as to not cause the fan to be actuated due to changes in the duct work temperature which are due to changes in outside temperature or causes other than the operation of the system. A sensor which is located in the duct work controls the operation of the fan in response to temperature changes only if the sensor control circuit is first energized by the operation of the system.

Hope help with this (remember rated this help).
