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)
GM Dealer quote: $281.00
I saved $219.31

Check Engine Light Diag EVAP Codes
This is a video of a 2006 GMC Sierra that had a check engine light & some
evaporative emissions codes. I show how to diagnose the problem with a
scan tool and the upgraded parts required to repair it. The codes in the
PCM were P0449 & P0455. I repaired it with a procedure in GM TSB
02-06-04-0374 that was to repair a restricted EVAP vent path &/or code(s)
P0446 / P0442. This problem could also result in a fuel tank that is hard

Explain the operation of the EVAP system. The EVAP system is in charge of
recovering the excess fuel vapors and re-introducing them into the engine.
It isn't just an emission system. If it malfunctions is also has a huge
effect on engine performance and certain components operation will be
cancelled by the ECM if the EVAP system fails. Learn how they operate here
and how to test. The OBD-II scanner or Scan-1 is used to diagnose these
systems and evaluate the process. See how it works.
