Course Description
This noncredit course is the first in a series of courses required by the Bureau of Automotive Repair (BAR) to obtain an Advanced Emissions Specialist license. The course will cover rules and regulations, history of the California Smog Check Program, a study of five-gas analysis, oxygen sensors, an overview of all emission control devices offered in California since 1975, and an introduction to second generation onbosard diagnostic system (OBD ll). The theory in this course is reinforced with hands-on skill practice. Students must complete this course before submitting an application to the BAR for an Advanced Emissions Specialist license. Noncredit. NOT DEGREE APPLICABLE. Not Transferable.

Writing Assignments
Students prepare for written tests through careful reading of assigned texts. Students use criticalthinking to analyze vehicle emissions systems, evaluate information, determine root cause, andperform repairs to reduce harmful emissions. Students use lab scopes, gas analyzers, serviceinformation, and other equipment to gather critical information to make diagnostic decisions.
Out-of-class Assignments
N/A
Demonstration of Critical Thinking
Students will diagnose emissions related concerns based on information gathered from test equipment, service information, and other sources. Students will demonstrate an ability to determine cause and effect, root cause, relationships of all data, and make repairs that reduce harmful emissions.
