I have warnings on dashboard for months ENGINE CHECK and EP red and yellow...computer reads "Mass air flow sensor 'Air flow too low' " - ODB code P00BC... checked intake hose and mechanic said its still good and recommend i change MAF sensor...so i did and ofc it didnt worked...afterwards he changed the map and o2 sensor and without luck...next thing he said i should go to Honda and do ecu software upgrade but im not sure is that even a thing ?
