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 Honda vehicles. The course material will be presented in a lecture/laboratory format and include videos, handouts, WBT and hands-on lab experience in the shop on vehicles. Students are required to complete assigned materials, take notes and be responsible for the information in the textbooks, lab manuals and electronic service information located at each of the work areas throughout the automotive labs.

Upon successful completion of the course, students should be able to:

1. Perform engine performance inspection, maintenance, diagnosis and repairs at an introductory level.

2. Demonstrate introductory-level knowledge of fuel delivery and emission control systems.

3. Perform diagnosis and repair of fuel delivery systems to professional and ethical standards.

4. Access and utilize repair information in an environment with rapidly changing technology.

5. ɳ°ÍÌåÓý¹ÙÍø and implement strategies and processes to solve engine performance problems.

6. Perform diagnosis and repair of electronic ignition systems to professional and ethical standards.

7. Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.
