This is an updated and revised edition to help student technicians get a commanding grasp of how computerized engine control systems work, what strategies are used in their operation, and how to diagnose problems within various systems. The student technician who studies this book will come to realize that no single component or circuit within any given computerized engine control system, other than the computer itself, is complicated. The book is dedicated to helping student technicians acquire the necessary knowledge to be able to diagnose and repair driveability problems with a computerized engine control system. The material is presented in a logical format, with the introduction dedicated to a review of electrical circuits and applications, and each following chapter discussing a separate computer controlled system. Each system is given thorough coverage, with enough specific information and detail to enable the reader to get a complete and clear picture of how the system works.
Frequently, information contained in a manufacturer's service manual is presented in this text to help make a specific concept more clear and to help acquaint the reader with information found in the service manual. This book should be of interest to student engineers, technicians doing courses on automotive technology, computer engine control systems, automative electronics and engine performance diagnostics.
