P24F3 - what’s the fix?

I just got my 2014 eco-diesel back from the dealer, I had to get a new thermostat housing. I had the truck for a few days, half a tank of DEF, half a tank of diesel. It was about 32° Outside, and the vehicle the code P24F3. I did it almost immediately upon start up.

I looked it up, and it means “reductant tank, temperature/fuel temperature correlation.” I am not sure what this means, my Internet search has been kind of fruitless, but I also I’m more interested as to what to fix might be. For what it’s worth, it’s been around the same temperature for a few days, the check engine light has remained on, but the vehicle seems to run fine.

Any thoughts are appreciated!

Check for cracks in the exhaust flex pipe
