Get to the root cause of EVAP faults more quickly with ATG's manual: Evaporative Emissions Systems: Leak, Flow & Function Testing.

"But I have a smoke machine"
This manual explains where the smoke machine fits into the EVAP diagnostic process, and when to jump to the next best tool & test combination to avoid wasting time or misdiagnosing. In the ATG tradition, the manual offers multiple options for testing each component and system to give you the testing flexibility you need.

#1 Trouble Code Category: EVAP
So many parts of EVAP Purge and Flow Monitors are calculated, and we don't get to see those calculations.  Instead, the flow charts tell us to check everything in the system in a linear diagnosis that takes too long when it works, and can actually prevent diagnosis by being too invasive and changing something in the system before the fault can be observed.

First, ATG shows you universal techniques applicable to every system, including:

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


By following ATG's procedures, you can avoid the technical nonsense that typically lengthens diagnostic times!

Second, if no leaks are found, ATG's procedures become more system-specific, but not yet manufacturer-specific.

Third, ATG has included manufacturer and system specific tips and tricks for those cases where the problem was not diagnosed in the prior steps.
