Portland Community College | Portland, Oregon

This course is designed for students with no previous industry experience. Students will develop the skills, knowledge and attitudes necessary to perform, with limited supervision, the appropriate procedures involved in engine performance diagnosis and adjustments on cars, pickups and vans. This course will prepare students for the Auto Shop Lab capstone courses which provide the opportunity to practice learned skills on customer and school controlled vehicles in a “working shop” setting. This will begin the skill level necessary for employment at an apprentice level.The course material will be presented in a lecture/laboratory format and include videos, handouts and hands-on lab experience in the shop. Students are required to read assigned materials, take notes, complete homework assignments and research information in service manuals and with electronic service information systems.

Upon completion of the course students should be able to:

• Perform engine performance inspection, maintenance, diagnosis and repairs at an introductory level.
• Demonstrate introductory-level knowledge of fuel delivery and emission control systems.
• Access and utilize repair information in a rapidly changing technology.
• Å·ÖÞ±­¾öÈü¾º²Âapp_Å·ÖÞ±­×ãÇòÍø-Ͷע|¹ÙÍø and implement strategies and processes to solve engine performance problems.
• Perform diagnosis and repair of electronic ignition systems to professional and ethical standards.
• Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.
