Hi there have this common code however customer already Googled & fitted gen maf!
Intermittent code, take a day to return with a flat,smoky engine & an egr "stuck open"
according to tech 2 this code description is air mass high input,
In live data koeo i get 12kg/h from the air mass
if mass removed reverts to 0 kg/h

load tested wires to ecm,good earth path,
scoped air mass idles at 2.4v up to 4.4 wot
also updated ecm software as precaution
