Yep, either air in the radiator fluid system, or problem with the radiator temp sensor or sensor connector.
When the car does not see a steady climb rate of the radiator fluid at warm up, it going to throw that message.
So if you just changed the raditor fluid, then need to vacumn the system tank to get any trapped air out of the system. Hence air bubble reaches the temp senor to cause a dip in temp reading, and causes the code problem.
If you did not just change the radiator fluid, then its the raditor temp sensor connector that you want to first unplug, clean, then put it back on since a faulty connnector contact will cause the same problem as well.
The temp sensor is on the drivers side head front side.
So see if just cleaning the connector resolves the problem.
If no, then may be a wire problem at the connector or wire loom that is causing the problem with the sensor not reading a steady increase in temp from the spastic connection.
Or could be just a radiator temp sensor on the way out, and easy enough to change as well.
