Designed specifically for the automotive lab environment, this training provides a practical roadmap for teaching EVAP system operation and repair. We focus on the "big four" components: canisters, purge valves, vent solenoids, and sensors, and how to demonstrate their interaction to students. The session includes a deep dive into OBD II logic and hands on troubleshooting tips that you can immediately integrate into your shop demonstrations to help students identify faults faster.
