jackfelixsmith Posted January 24, 2016 Share Posted January 24, 2016 99 Glanza V . Engine management light came on . Ran the self diagnostics and got fault code 31 . Witch is the MAP sensor .. Ive tried three different map sensors and cannot get the light off or the car running right.. car Idles lumpy rev's to 4000 or 5000 then just starts to drop, and now and again just cuts out .. Tried 3 different sensors and removing the EFI fuse and the battery leads with no luck .. has anyone had the problem before and fixed it another way ? Thanks for any help !
