There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.
The ohter is under the dash and above the pedals, this one is much tougher to access.
Your Owner's Manual should tell you where the fuses are that you need to access.

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

It is with a 2 wire Black connect located next to the throttle body. Locate the green cap on the evap hose and follow it to the throttle body and that is the purge valve.

The canister purge valve is located behind the intake manifold in the engine compartment on the firewall side .It should be a small round solenoid with a wire connector attached.It will have a feed hose from the evap cannister to the purge valve and then to the intake manifold.The evap canister is located on under the vehicle on the right side of the gas tank and is held in place by a bracket.If you follow these hoses it will also get you to the canister purge valve.I hope this helped.
