Replacing Vent Valve Solenoid & Purge Valve Solenoid (EVAP Valve) 2005 GMC Yukon
When you get a check engine light, your parts store can test it with a
little electronic device - ask for the check engine light tester.
They go by many names, but look for EVAP Valve or Vent Valve/solenoid &
Purge Valve/solenoid. The one in the rear of the car, near the gas tank, is
known as the "Vent Valve Solenoid Canister." The one in the engine
compartment is called a " Purge Valve Solenoid."
Replacing the one in the engine compartment did the trick. I'd start by
replacing that one first then test it.
$25.97 Vent Valve Canister (fuel tank one)
$35.72 Purge Valve (engine compartment one)

Valve - P0446 - testing and replacement.
The EVAP canister vent control valve is located on the EVAP canister and is
used to seal the canister vent. This solenoid responds to signals from the
ECM. When the ECM sends an on signal, the coil in the solenoid valve is
energized. A plunger will then move to seal the canister vent. The ability
to seal the vent is a necessary part of the diagnosis algorithms for other
evaporative loss system components.
