P20BA
The code P20BA came up on the dash and after checking it was the heater in the def tank,i checked and found the 25amp fuse had blown so i changed it and the code went away,after travelling 500 miles the code came back on,checked the fuse and it had blown again,anybody got any feedback on the issue.

Your truck year? Mileage? It might be the DEF heater itself. There was an extended warranty of the DEF heater for some models. Contact the dealer with your VIN and see if you might be covered.
