So I got the “def quality poor” message with the mileage countdown to limp mode, no CELs to be read, none on dash, none stored per obd2 scanner.
Ive replaced pos 2, pos 1 should show up any day now.
Which is the best way to clear the light if there are no cels showing?
Gm drive cycle? Better to do it with the obd scanner?
been following the older def threads but no activity.
Any info appreciated, thanks!
