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

Automotive Evaporative Emissions - Part One
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
vacuum leak detection.

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.

The Message Center on the dash of my 2000 Chevy Suburban was displaying
'Service 4WD'. The message would come and go. There was no error/trouble
code set in the truck's computer when I used an OBD-II reader. This video
shows you the quick (5-10 minutes), effective and inexpensive (approx. $50)
fix for this problem.

*This video is an EXPERIMENT I wanted to try on my car, and is for
INFORMATIONAL purposes ONLY. This fix is for off-road use. The content

I enjoy the process of testing theory because you always learn something
new, regardless of the outcome.
Using a spark plug defouler kit, I install a "buffer" in between the
downstream oxygen sensor and the catalytic converter. Quite often,
frustrated car owners get the P0420 code for reasons other than a bad cat.
I have heard of people getting the code just because they removed the
converter and reinstalled it. It can also happen if you run your vehicle
out of gas etc... etc...
It is also common for car owners to get the P0420 code, replace the
converter, and both o2 sensors-- only to have the code come back after 1000
miles or so. This can be a very frustrating, time consuming and of
course-- expensive venture. Here is one way to resolve the issue. Good
luck and have fun!
