I have a 2006 Ram 1500 4.7 with 233k miles. Sometimes the coolant temp sensor will fire a code while the Temp gauge reads below 50%. It has a new Mopar Coolant Temp sensor installed but continues to do this randomly. If I stop and restart the engine the code clears. If not the truck reacts and doesnt run its best. I havent been able to find any answers.
Thanks in advance for any help you can give me

You either have a bad temperature sensor (even though it's new) or a malfunctioning thermostat (it's 16 years old) or both.
What's the code? The computer expects a functioning thermostat to keep a certain ECT (temperature) level.
A bad thermostat can trigger an ECT code when it isn't closing all the way and causes the engine to run cooler than the computer expects
the coolant temp sensor will fire a code
which is?
