I am having more problems with my newly purchased 2014 2500 with 61K on it. I got the P20EE code and trying to figure it out. Background - I bought the truck a couple of weeks back From an older couple [ older than me and I'm 81] that seldom drove it after selling their 5th wheel camper. They filled with DEF last winter And it has sat most of the time since they have a smaller car with better mpg.
With it setting all summer outside in high temp would this make the DEF go bad and cause the P20EE code? I plan to buy fresh, find out how to drain and blow out lines. I hope this is my problem so I can sell it and go back to my 2004 that is a lot simpler.
All help is greatly apricated.
