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.

$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.

Some EVAP leaks can be hard to find. But usually "large" leaks can be
spotted pretty quick. Here's the way I've been finding them with a simple

From www.autofixworld.com: Part One of a two-part video describes how
onboard monitors test vehicle fuel containment systems for fuel vapor
leaks. Three types are discussed: pressure test; vacuum test; and natural

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
Purge valve solenoid repair on 2007 trailblazer
Hi everyone, this is my first video so I apologize in advance for the video
being so long. Working on my truck is my new hobby and I love it. All that
I have learned so far has been from the great people who make YouTube
videos. So cheers to you all.
Hopefully this video will help at least one person.
The problem code that came up was po496, the symptoms of my car having
problems were hard start when filling up gas at near empty tank, gas pump
would constantly shut off during filling up. The previous codes told me it
was a gross leak so I changed the gas cap twice and it did not help so
after all my research. This is the part that needed to be changed out. It
cost around $41 at o'rielly for the part rock auto had it on line for half
the price if your willing to wait.
