Course Description:
This course will provide an in-depth analysis of the various electrical systems utilized in the modern automobile. Students will receive classroom and lab instruction on electrical theories and its application to the emissions systems. Emphasis will be placed on the emissions components of the major automotive manufacturers.
Prerequisites/Corequisites: A student is to have completed all prior program courses with a “C” or better grade. Any exception will have to be approved in writing by the Program Coordinator and Department Chair. Because of changes in technology, students taking program over an extended period of time may be advised to retake courses to update skills and competencies.

Course Objectives
Emissions Control Systems Diagnosis and Repair
1. Diagnose oil leaks, emissions, and driveability concerns caused by the positive crankcase ventilation (PCV) system; determine necessary action.
2. Inspect, test and service positive crankcase ventilation (PCV) filter/breather cap, valve, tubes, orifices, and hoses; perform necessary action.
3. Diagnose emissions and driveability concerns caused by the exhaust gas recirculation (EGR) system; determine necessary action.
4. Inspect, test, service and replace components of the EGR system, including EGR tubing, exhaust passages, vacuum/pressure controls, filters and hoses; perform necessary action.
5. Inspect and test electrical/electronic sensors, controls, and wiring of exhaust gas recirculation (EGR) systems; perform necessary action.
6. Diagnose emissions and driveability concerns caused by the secondary air injection and catalytic converter systems; determine necessary action.
7. Inspect and test mechanical components of secondary air injection systems; perform necessary action.
8. Inspect and test electrical/electronically-operated components and circuits of air injection systems; perform necessary action.
9. Inspect and test catalytic converter efficiency.
10. Diagnose emissions and driveability concerns caused by the evaporative emissions control system; determine necessary action.
11. Inspect and test components and hoses of the evaporative emissions control system; perform necessary action.
12. Interpret diagnostic trouble codes (DTCs) and scan tool data related to the emissions control systems; determine necessary action.
