I would start by reading the codes to see what comes up but to me it sounds like the engine coolant temperature sensor needs to be replaced. Here are some guides to give you an idea of what needs to be done to get us started.

Here are some diagrams of what it will take to change the sensor (Below)

Please let us know what happens.
