COOLANT THERMOSTAT CODE
i have three codes constantly popping up as soon as i go over 60 does anybody know?
i have shown this to a few mechanics they don't think it's the convertors
could it be pressure sensors?
baby name suggestions based on parents names

I had the same set of messages. Replacing the thermostat cleared up the problem.
Have you watched your coolant temperature to see if it is running low? Low coolant temperature may not be quite as obvious now that the weather is warming up. But I was able to verify that the thermostat was not functioning correctly by watching the coolant temperature, and I noted that it was running lower than it previously had.

Bad thermostat
Your thermostat is probably stuck open, not allowing engine to reach operating temp quickly enough, thus setting the code
