You will have to replace the temp sensor,for this,and hate to say this ,but it is only a dealer item,you can try to dissconnect,battery cable for a few minute,s and see if it will reset,if it dosen,t,then replace sensor.

Yes he's right it is the temp sensor, But there's good news, you can pick it up from the dealer for about $13.00...easy to install, it's right by the radiator,buy it and replace it your self, it's called a EXTERNAL TEMPERATURE SENSOR and save some$$$$$$ hope this helps
