Mass air flow sensor replaced?

Ok yhe power outlets for phone chargers are controll by a 15 amp mini fuze its located in the fuze pannelunder the passengers side glove box its blue I think it ine position 45 ..but it should show on the inside if the cover..and as for the check eng light ...it would be best to scan it ..if you dont have a scan tiol they usually scan it for you for free at alit of autiparts store s that a good place to startgood luck hope this helps

If you changed the mas air flow sensor than you can keep driving it and somtime in the next 50 miles or so it might just go out on its own..the other alternative would be to just turn out the check engine ligh with a scan tool and since the part was changed and the problem was most likely solved solved it shouldnt come back on again good luck .
