Hello all,
I have the DEF service warning light saying that my truck will not reset after xxmiles. I had code P204F, I removed the DEF injection nozzle and cleaned it (it had lots of crystallization on it). I cleared that code then I drove it some more <20 miles, and the check engine light came on again. Now I have 2 codes both are listed below.
I have AlfaOBD so I can do a lot of things just don't know the steps to use on AlfaOBD to check DEF pump and injector.
I think that the DEF line might be frozen because the DEF heater for the DEF line has failed.
Does anyone have the procedures or steps to turn on the DEF pump so that I can check things?
Any help would be appreciated thank you.
