Engine Controls - Theory & Operation: Introduction: Terminology
Because of Federal government requirements, manufacturers may use names and acronyms for systems and components different from those used in previous years. The following table will help eliminate confusion when dealing with these components and systems. Only relevant components and systems whose names have changed from current Ford Motor Co. terminology have been listed. See REVISED TERMINOLOGY table.
