The car has 283,000 miles and the engine runs strong. I keep getting the code PO116. Put in a new oem sensor. Still getting the code yet my scanner shows the coolant temp at 30 degrees when it's 190? New Thermostat didn't help!

What is your question?

Car has 283,000 and runs strong. Did the timing belt and new water pump about 7,000 miles ago. What could be causing this problem with the code showing up at random times and only showing 30 degrees when it's hot? It's the OEM green square connector coolant temp sensor that I installed and didn't cure my problem. Detail help would be greatly appreciated.
