EECS Incorrect Purge Flow?

What is this caused by and how can it be fixed?
"P0441 Evaporative Emission Control System Incorrect Purge Flow"
Could it be as simple as replacing the PCV valve?
Thanks.

No. EVAP uses a vacuum to draw 'fumes' out of the plenum area into the charcoal cannister. Id look for a burned vacuum line somewhere or depending on system, a bad check valve. The is pretty much a generic OBD2 code you gave, can you be more specific on what it came from?

The code is from a 1998 Hyundai Elantra.
I'm in the process of trying to find out where exactly the purge solenoid valve is and the canister so I can check it.
