EVAP Diagnostics and Case Studies

Dive into the complexities of EVAPorative emissions systems across domestic, Asian-Pacific, and European platforms. This course covers both pressure-based and vacuum-style EVAP designs, highlighting diagnostic techniques that go beyond the basics. Learn how to identify leaks using pressure testing, smoke machines, and CO2 detection - and compare those results with onboard bl-directional tests. We'll explore scan data interpretation, global OBD Mode values, and the tools that make diagnostics more accurate and efficient. You'll also see how EVAP behavior and testing strategies shift between naturally aspirated and turbocharged applications, giving you a complete picture of system performance and repair.
