Where is the 2015 ford edge purge valve located?

The purge valve on Your 2015 Ford Edge can be found on the evaporative canister that is located above the rear muffler. The purge valve is there to release vapors when they build up in Your fuel system so that they do not cause a blockage or knock. The valve also helps clear out the EVAP system when the pressures get too high in that. If there is a problem with Your purge valve usually it will be with it getting stuck open. This will lead to a check engine light which will come back with a code for an EVAP system leak. If You have tested Your gas cap then the next most likely problem is the EVAP purge valve.
