Hello where are you located? I have a 2008 Chevy Impala with lean code. We cannot find issue. Are you in NY?
Absolutely critical to know without question it's DONE! Something I have failed to do countless times…love this…thanks Keith!
Quick & value, thanks Keith
I agree with David Kittle, Thanks from Me too..a 62yr old man who has been wrenching on my own junk since I was 16. ALWAYS a learning experience with New Level Auto, PHAD, Simply Diagnostics and South Main Auto. You guys are helping sooo many people. God Bless all.
You are like Batman with all your tech toys!
Keep it up from Aleskyfinis
Good stuff Keith! Isn't it silly that the Tech 2 can't auto-ID a GM vehicle, while all aftermarket scanners do that no problem? 🙂
Good description Keith. Exactly how I learned to do this at the GM dealer many years ago.
Thank you Keith. Good job again. Question, non-intrusive versus intrusive leak test. Is non-intrusive only during key off natural vacuum leak test? Intrusive is large leak testing with engine running and purge is being used for the testing? Is non-intrusive only used on systems like Fiat, Jeep, Chrysler Dodge ESIM, NVLD Systems? Or are there other Makes that have non-intrusive testing?
@New Level Auto, when you verify your fix on GM EVAP systems do you normally pull vacuum all the way to near
10 InH20 or do you just pull as little as you did in the video? or do you primarily just focus on the FTP sensors voltage? I ask because I have a 04 Trailblazer w/ P0455 Large leak and cannot locate the issue. I have a Tech 2 and EVERYTIME I do the Purge/Seal test, I usually pull a vacuum to near -10 InH20 then seal the system. When I do seal the system, the vehicle stalls IMMEDIATELY and all vacuum shoots down. Am I pulling more than the PCM would naturally pull for the test and do you have any suggestions as to what I can test next to finally get rid of this issue? BTW, the fuel trims are @ normal, purge is relatively new, the vent valve does click both on and off and FTP sensor has movement, but with a engine @ operating temperatureif I just seal the system to see if pressure builds upward, no movement. Any help would be greatly appreciated. Thanks in advance.all good info
Nice job again like always
Toyota evap systems way more complicated with all the vsv and orifice. Gm is the easy cash
Great video. Very informative and full of knowledge. Thanks for sharing.
