You will need to remove the right front wheel & wheel well liner. The canister purge valve is behind the cover. It should have two tube going into the bottom and one on the side near the top.
You can fix it!
If this helps you out please rate me!

That is an EVAP code. its a vent control code. you can manually test it by powering it up if you know where its at. i cant remember exaclty where its at off the top of my head but its only 2 wires. using a volt meter you want to make sure power is getting to it, but you cannot activate it without dealer scan tool.hmmm if you can figure out which is ground and power when you give it 12 volts it should click. meaning your vent solenoid works and you have wiring problems or its leaking.
EVAP problems are hard to finde with out scanners. you can change the vent solenoid and hope it fixes it. but a code points you to the direction of a problem. hopefull its not wiring problems. in the northern states with snow. ice can pull out wires and also get clogged in the vent solenoid and lock it up. its either wiring or bad or a leaking solenoid. check condition of wires. if they look good try a vent soleniod.
if that doesnt fix it after a engine light reset and 2 weeks or so. then goto dealer. you need to reset it after repair. light will not go off on its own.GOOD LUCK

Tips for a great answer:
An EVAP canister, vent hose, or vent solenoid valve that has restricted flow may cause this DTC to set. Using a purge solenoid command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the engine running, the EVAP canister vent solenoid valve open, and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 5 inches H2O.
An EVAP canister filter that is restricted can cause this DTC to set. Refer to Evaporative Emission Canister Replacement .
Disconnecting one component at a time while the EVAP system is under flow will help to pinpoint a restriction in the system
Do you have a scan tool that reads data PID'S ?
Your FTP - fuel tank pressure sensor could be at fault !
