I'm working on deleting 2013 lml. I removed dpf and installed new pipe section. Got all that working and made a couple test runs. When I park, before turning truck off there is no MIL light. When I restart I get a MIL light P140F and P1407. I looked those up they are EGR related. I havent messed with EGR yet. I'm wondering why it keeps coming up.

P1407=EGR motor control shorted
p140f=EGR motor current performance

Any ideas?
