OEM flowcharts routinely make EVAP system diagnostics too complicated.  Despite the wide variety of systems out there, our research has revealed that a layered approach is much faster than the linear OEM approach, leading to a profitable diagnosis without the wasted (and unbillable) diagnostic time or multiple trips for your customer.

This is the 2nd subject in our Import Series, but also comes with a thick Domestic section. First, we show you universal techniques applicable to every system.  If no leaks are found, the procedures become more system-specific, but not yet manufacturer-specific. All systems fall into one of four categories listed below, and by following our universal procedures, you can still avoid the technical nonsense that typically lengthens diagnostic times! Most faults are found using these first two layers. We have also included manufacturer and system-specific tips and tricks for those cases where you’ll need to go that deep.  System coverage includes:

  • Traditional & Split Purge/Seal Systems
  • Leak Detection Pumps (KOER & Key-OFF)
  • Natural Vacuum (EONV, NVLD, ESIM)
  • DMTL (comparative current flow)

At the manufacturer and system-specific layer, Scan Tool PIDs and controls are inconsistent. While we cover them all for you, we also discuss the back-up plans that may involve a power probe, jumper wires, a gas analyzer, Mode $06, or other simple tools and methods to get your EVAP system to give up its secrets.

From a simple high-level pass to system-specific tips, this seminar covers the entire diagnostic process. We have included dozens of real-world examples to prove that these strategies work quickly on the vehicle’s first trip into your shop.  We are confident that this seminar will enable you to be a lot more successful in finding leak or flow codes, and in verifying proper component functionality.


Mission: To provide superior quality training and create industry-leading programs that produce consciously competent technicians that provide safe and proper repairs of current and future automotive technologies.
