SPN 3031 error code
Has anyone had any experience with this code?
Spartan said it is a DEF temperature sensor. They said to wait to see if it manifested into anything else.
I went on a 3 hour trip and returned with the check engine light on the entire time. It even did a regen on the way. When I went to park it in the barn after we got back the light had gone out.
I am wondering if this is something that will turn back up. Spartan said these things don't usually repair themselves.
