If you lost heat, make sure the coolant level is full. If it is, replace the t-stat. Next, check the right front of the head (driver's side) if there is a head gasket problem, that is where they always seem to start leaking. Also, after you replaced the sensor, did the same code come back? Finally, are you sure the car is overheating and this isn't being caused by a bad temp sending unit? Does the coolant boil out of the radiator? Can you hear it boiling in the engine?
Let me know.
