This course will carry the student beyond basic tune-up into the world of computer controlled systems. Students will study the engine sensors that feed data to an on-board micorprocessor. They will learn how the microprocessor processes and then uses data to make a host of real time decisions concerning the correct delivery of fuel, ignition, and emission controls to achieve maximum fuel economy and minimun emissions output. Students will get hands on training on late model cars to reinforce classroom theory. The use of scan tools, computer self-diagnostics, and electrical principles will also be covered. The primary content of this course is directly related to an Automotive Technology occupational program.
