According to the FSM the code is for the Evaporative Emission Control System Incorrect Purge Flow

Possible issues:
Open or short in VSV circuit for EVAP
VSV for EVAP
Open or short in vapor pressure sensor circuit
Vapor pressure sensor
Open or short in VSV circuit for vapor pressure sensor
VSV for vapor pressure sensor
Vacuum hose cracked, holed, blocked, damaged or disconnected
Charcoal canister cracked, holed or damaged

What tripped the code:
The pressure int he charcoal canister does not drop during purge control
-or-
During purge cut-off, the pressure in the charcoal canister is very low compared with atmospheric pressure

Check your vacuum lines. If it isn't a problem with those, I think your VSV valve would be the most likely cause.

Replace your gas cap, disconnect battery and see if the check engine light comes back on. I had something similar and fixed it this way. $25 fix.
