My 2016 Ecodiesel threw this code today. From what I’ve read and the service guy said it’s either SCR or NOx sensor. He said if it fails the truck will give me a range till it enters limp mode. They were backed up but I can get it in Monday. Should I just drive it as normal and see if the notification comes on? I took it to orileys first to have them check it, there were 3 P20EE codes and 2 of them cleared where the 3rd was permanent. Check engine light didn’t come back on.
