Butler-assessed Outcomes
The intention is for the student to be able to:
1. Verify engine mechanical integrity.
2. Identify and correct fuel and induction system concerns.
3. Identify and correct problems related to the ignition and exhaust systems.
Learning PACT Skills that will be developed and documented in this course
Analytical Thinking Skills
Critical thinking – By applying logical/sequential thought processes to formulate
solutions for engine related concerns. The student will utilize appropriate electronic
tools in the diagnostic process and solve system problems.
