DEF 2011 up

Is there a DEF TROUBLESHOOT section or discussion, something that provides pinpoint test recommendations based on codes??
replaced pump and sending unit/tank heater. Keeps throwing same codes. Worked awesome for 3 days after clearing codes p208b, p208c. Suspect I have a wiring gremlin....

you might check all the connections and clean them and ensure they have good contact.

I’ve tried that on the tank end.. need guidance or pinpoint tests for specific codes to go further.
All in all, replaced heated line to injector, pump/sending unit and tank heater.
P208b/c have nothing to do with injector hence leaves wiring.
Looking to delete the bs to be honest. Every 2 yrs I go though this.

Check with your dealer. There is an extended warranty on the DEF heating system. Your truck might be covered.
