Description

This workshop is designed to aid technicians in the understanding of how to diagnose and repair today’s Evaporative Emission Control Systems. We will cover several types of Enhanced Evaporative Emission systems with a focus placed on Leak Detection Pumps (LDP) and Evaporative System Integrity Modules (ESIM). We will also discuss operating strategies for Engine Off Natural Vacuum (EONV) systems and Natural Vacuum Leak Detection (NVLD) systems. Leak testing procedures using smoke test equipment will be reviewed. Diagnostic methods for quickly pinpointing the cause of common EVAP DTC’s will be highlighted. This workshop includes hands-on bay activities supporting the aforementioned topics. After completing this workshop, the student will have the knowledge to: Identify the type of enhanced EVAP system being diagnosed Use the OBD II monitors to aid in diagnosis and testing Utilize scan tool bi-directional controls for testing Test for small and large EVAP leaks using smoke tests Determine the most effective and time saving ‘next step’ in the diagnostic process
