I have a 2017 with 2500 miles same code took it in low exhaust temp, it was 17degreesF this morning. The code is not active but stored so they said it should go away. Anyone know what causes it?
Thanks for the welcome just got a 2017 ram eco and all my friends with Cummins and power stokes all run additives to lubricate the fuel system and increase cetane due to dry US fuels, they run Howes and Stanadyne. Thought for the eco?
