CEL but no DTCs detected?
I'm seeing a permanent CEL on my dash, but upon doing a vehicle DTC scan via the EcuTek app, I don't see any codes displayed.
Oddly enough, performing the OBD readiness scan does show "1 emissions-related DTC" next to the CHECK ENGINE checkbox, but it doesn't provide me with any way to view it. Any ideas on why I can't see the code? I cleared all DTCs just to see if it would come back, and nothing showed up after a 10 min cruise around town.

Tune related most likely.

Get a different scan tool or go to autozone and borrow one. I have a feeling its p0420 and it might be a tune issue

Delicious probably forgot to turn off the emissions related codes in the tune.

Are you flex fuel with pressure sensor? Could be fuel pressure related to the D box.

If it's EcuTek tuned then it could be that the CEL is set to come on for some reason when a Custom Map is triggered. That will not pop a code. EcuTek is normally very good for viewing DTCs.
