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





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.

In charge of sensing fuel tank pressure during an EVAP monitor event, this sensor is the heart of this system. Learn how to test each electrical output and input terminal, voltage tests, reference and ground. Also, we'll show some peculiar facts about this sensor. See it all here with this training video. *************************************************************************** *********** 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





EVAP System Operation
EVAP System Operation Amazon Printed Books https://www.createspace.com/3623936 Amazon Kindle Edition http://www.amazon.com/Automotive-Testing-Diagnostic-Strategies-ebook/dp/B00 52YFOCI/ref=sr_1_2?s=digital-text&ie=UTF8&qid=1360016628&sr=1-2&keywords=se nsor+testing%2C+mandy+concepcion Android APPs https://play.google.com/store/apps/details?id=com.app.book.AOTLVEWIWPXAXYGM Z&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hcHAuYm9vay5BT1RMVkVXSVdQ WEFYWUdNWiJd 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. *************************************************************************** *********** 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





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.

My 05 Chevy Avalanche P0449 Code Cure.wmv
My Check Engine Light came on in my 2005 Chevy Avalanche Z71. Used a code reader to find P0449 code. Did some research and found out the purge valve for the emissions system can cause this code. This is how I fixed mine....





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





How To Test and Replace EVAP Canister Vent Control Valve P0446
Click Here to Subscribe! http://youtube.com/carsntoys Website: http://carsntoys.net Evaporative Emission (EVAP) Canister Vent Control 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.

Evap large leak smoke test
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 smoke machine.





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.
