Summary

Completely updated by an ASE Master-certified Automotive Technician, the sixth edition of Computerized Engine Controls explains how computerized engine control systems operate and translates these concepts into proven-effective diagnostic approaches. Tackling both domestic and foreign engine control systems, the book begins with an introduction to common engine control components and features an entire chapter on OBD II. Chapters that follow explore the ?ins? and ?outs? of important multiplexing and diagnostic concepts, introducing readers to diagnostic equipment and tests that allow quick identification of problem areas in computerized engine control systems. An excellent source of up-to-date information, this book also provides a solid foundation for expansion into light duty/gasoline or heavy duty/diesel applications.
