Check engine light with fault code

[jnowell]

Has anyone else experienced this? Just fueled up, got about 30 miles down the road and light came on.

Freightliner 450, check engine light with fault code 3582

What was your resolution?

Thank you

I just looked at your code. It is "after treatment SCR catalyst efficiency-data valid but below normal operating range-moderately severe level" Just a guess but it sounds like a bad sensor. At any rate a trip to Cummins is in your future.

You can look up codes on the Cummins Quickserve web site. https://Quickserve.cummins.com
