Question type: Maintenance & Repair

Service engine soon came on in 2003 Ford Expedition, Had the computer read, got the code and changed the appropriate part(s) but the light won't go off. Mechanic keeps telling me it will reset itself after a number of cold starts

Don't know why he did not reset it, he should have, but I would have to know what the code was to see if the light would turn off or not, but the code will stay stored in the computer until it is reset.

Unhook the battery for a few or cake it the AutoZone have them look it up and turn their head while you hit delete LOL


Also it will not go away it will always come back on if it's not deleted from the memory hope


I did mention that, thanks for repeating.
