EVAP Code P0449
Here is a description and how to diagnose EVAP code P0449





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. Cost: $25.97 Vent Valve Canister (fuel tank one) $35.72 Purge Valve (engine compartment one) TOTAL: $61.69 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 to fill.

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. *************************************************************************** *********** Amazon Printed-Books & Kindle: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&fiel d-keywords=mandy+concepcion Google Play Android APPs: https://play.google.com/store/search?q=mandy+concepcion&c=apps Amazon Video DVDs: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dmovies-tv&field -keywords=mandy+concepcion Barnes & Noble Nook: http://www.barnesandnoble.com/s/mandy-concepcion?keyword=mandy+concepcion&s tore=allproducts Apple iTunes iPad: http://itunes.apple.com/us/artist/mandy-concepcion/id449573393?mt=11

How To Fix & Repair an Electrical Connection / EVAP Purge Canister Vent Solenoid
How to fix and repair an electrical connection. My EVAP purge canister vent solenoid code is coming up as a trouble code. Checked the wiring from the body connector and found this corrosion present. Tried cleaning the connectors with a metal pick and some soda pop. Jury is still out on if this will fix the issue. Will wait to see if the check engine light comes back on.

Clear check engine light for less than 5 dollars
More Tutorials on my CHANNEL: http://www.youtube.com/user/moccina *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 shown in this video is not intended to encourage emissions test cheating. 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!
