Description:
Students will Learn the theory and operation of OBD II evaporative emission systems. This will help them develop an understanding of why evaporative emission control systems are required. This course will help develop the critical thinking skills needed to accurately diagnose and repair emission control system failures.
What you’ll learn in this course:
This course will introduce the principles of the evaporative emission system. It explains the concept of gasoline evaporative fuel vapor (running loss, diurnal, hot soak, and refueling) from the vehicle gas tank to the fuel vapor stored in the carbon canisters. You will learn the purpose and operation of the various OBD II evaporative emission systems. Understand how to diagnose evaporative emission system related problems resulting from malfunctions in the various fuel system components; and determine necessary action. Students will also need to demonstrate correct and safe diagnostic repair procedures related to evaporative emission system failures.
