Engine Controls - System/Component Tests - 1.6L: Introduction: Terminology
Due to federal government requirements, manufacturers are required to use the same names and acronyms for similar systems and components. The Society of Automotive Engineers (SAE), in an effort to standardize automotive terminology, has renamed components and systems that preform similar functions. The following SAE TERMINOLOGY table will help eliminate confusion when dealing with some of these components and systems. Only relevant components and systems whose names have changed from current General Motors Corp. terminology have been listed.
