Four of 10 codes retrieved involve evaporative emissions systems (EVAP) codes. Delphi’s Greg Moyers, courtesy of Advance Auto Parts Professional, will conduct Diagnosing & Repairing Evaporative Monitor Failures at Auto TECH expo, April 3-5 at the Hyatt Regency O’Hare in Chicago.

Designed for intermediate and advanced technicians, this class covers the EVAP system, its components and the techniques needed for timely diagnosis and repair.

EVAP systems are mandated by the federal government to control emissions of volatile organic compounds. This Auto TECH expo course covers various system requirements to help with understanding why the malfunction indicator lamp (MIL) illuminates and the criteria for setting a code. Technicians also will become familiar with systems that use a pump and those that do not. Trying to locate a 0.020-inch leak can be difficult, so Greg will cover the required equipment, procedures and safety precautions. He also will present industry case studies that prove monitor theories and diagnostic techniques.

Technicians attending this seminar will learn about EVAP systems (including operation and function); OBD-II EVAP monitor components, tests and pump systems; the criteria affecting the EVAP monitor; OBD-II EVAP diagnostic trouble codes and EVAP scan-tool diagnosis; tools and techniques for EVAP leak diagnosis; testing for insufficient EVAP flow; EVAP service-bay tests; drivability concerns with EVAP systems; oxygen-sensor operation with EVAP systems; using OBD-II monitors to diagnosis and verify repairs; and diagnosis of evaporative-emissions components.
