Went to Autozone Check engine light came on with this reading from autozone:
PO118- Engine Coolant Temperature

So im thinking its the sensor for the thermostat not the sensor for the guage?

 

Usually with a engine coolant code you either have a sensor that has gone bad, or the thermostat has gone bad. change your coolant temp sensor and thermostat, reset code....should fix your problem. I say this because I worked at Advance Auto for about a year, 8 times out of ten it was usually a thermostat that failed, or the temp sensor went bad..just make sure as a precaution for your new sensor to use some dielectric grease..

 

I have just recently replaced the thermostat

 

K thanks for the help
