Question

With DTC P20EE on a 2012 Dodge Ram 3500 6.7L. What should I do next?

Answer 1

Possibly the filter on the def pump. I'm in front of the parts store with the same code. Going to see if they have it or it may be a dealer only part like most of the parts on the 5500's. :P

Comments

We have a fleet of 26 trucks, we have 7 Dodges with this motor and DEF system.  We are currently in the middle of an issue with the same code P20EE on a few of the trucks.. The dealer has already replaced the Catalytic converter, now they are saying the SCR needs to be replaced and it is not going to be covered under warranty..  I am curious if anyone has a confirmed resolution to this matter?.

Thank you in advance,

** For the 2011-2012 Ram 3500, 4500, and 5500 there is a factory service bulletin that recommends replacing the Selective Catalyst Reduction (SCR) Catalyst assembly if exhaust fluid leaks are found or there are no signs of DEF fluid contamination found
