Overheating Scare

Overheating Scare
65 degrees Blue Skies in South Louisiana today. Put the top down and go for a ride. Cruise Control set at 74 on Interstate. CEL and Restricted Performance come on at the same time. Looked at Temperature Gauge and it's in the Red. Pulled over. Opened the Hood. No Steam no signs of Fluid leaks. Engine actually seems to be running cooler than normal. Get back in the car and start. Everything normal. Go about another 20 miles and it happens again. Stop and check. Everything seems normal. This happens once more before I can get home. Normal again. Check for Code when I get home. P0116. Any suggestions on where I should start or change.
Thanks for any help.

With a $10 Bluetooth code reader (search 'ELM327' on eBay) and an Android phone or device running the Torque app you can read the temperature the ECT sees.
Do not drive the car until this is resolved. Overheating can seriously damage this aluminum alloy engine in a flash.
Consider RealGauge once the problem is resolved so you can keep better tabs on the cooling system, and have an audible alarm for overheating and low oil pressure in addition to a true analog temperature readout.

You should have a coolant system pressure test run. That usually locates the source of small leaks.

Pulled the Thermostat Housing to change Thermostat. I can't figure out how to remove the old Thermostat from the Housing. 2003 XK8 Vin SAJDA42C432A34419.
