Live data voltages are good on everything when plugged in . unplug after codes cleared ghost returns?? Anyo e have any ideas?

pin OBD 4&5 together and get back to us. Old Hondas do this all the time after a valve cover gasket replacement by the homeowner that leaves the ground off on the cover! your scanner is actually jumping those pins to get a bad ground regrounded. I give those chinese android code readers away, $3 ea on alli b. kill 2 birds with one stone, ground and education.
