    The #1 best diagnostic video on this issue...thank you 😎👍🏾
    There's absolutely no way I can not remedy this code myself now.

    If you have an Isuzu NPR (Chevy 6L engine) this is the problem too. Changed out both solenoid for a piece of mind and no more engine code.

    Thank you for the excellent video! this is the best most concise information I’ve received in three days of googling for an answer. My Chevy dealer has reset it twice for free however three or four days later the engine light shows up again. He told me 449 was a code for the sensor and that I could just buy one and put it on myself or they could do it. My particular 2009 Silverado had some sort of governor on it to where it’ll never let me go over 100 miles an hour. Interestingly, or coincidentally the engine light always shows up when I hit 100 miles an hour and a slight stalling sensation occurs. Not sure if this is a clue or just weirdness. What think you?

    Great video. I can only put in like $8 before gas spills out. The gas station pump nozzle not clicking. But I don't know why my gas tank is refusing to accept more fuel? I've checked all hoses and charcoal canister. Everything is intact. My gas gauge is always showing full. Can a bad gas pump and sending unit be the culprit?Any help would be greatly appreciated. Thank you

      That is a common symptom when the vent valve is stuck shut. The vent valve is usually located in the charcoal canister or very close to it.

    I got a p0449 code. Replaced the evap solenoid(definitely was bad). Code came right back after deleting code. Replaced gas cap with new GM cap and now the code doesn't come back until I remove gas cap for refueling. Canister bad? 2005 chevy Colorado. Any help would be appreciated.

      A flashing engine light is usually a SERIOUS problem. Get that checked asap.

    Does this code usually throw a p0455 as well? Large evap leak

  • @charlieyeager3645
    @charlieyeager3645 8 หลายเดือนก่อน

    Would it be a clue that the only issue the code causes, other than the CEL staying on, is it doesn't start very well, but only after I get gas...?

    • @HVAC_Mechanic
      @HVAC_Mechanic  หลายเดือนก่อน +1

      Usually, no; if the purge valve is stuck open, it can affect the engine, but usually, it just won't pass an emission test.

    Could the issue for this code ever be derived from the ECM not sending a turn on signal to the vent solenoid?

    • @HVAC_Mechanic
      @HVAC_Mechanic  4 หลายเดือนก่อน

      Yes, an open wire that doesn't send the signal to the vent valve will cause issues.

    It's funny my 07 suburban has a aftermarket stereo that does obd clearing the truck throws the code when the outside temperature is above freezing. If I clear it below 32° it stays cleared until the ambient rises above freezing. Then it throws the code.

    just now watching this , what I hate is the "it COULD BE ..." phrase .. buying all these parts and the problems be still there .. no different than the bodies we walk in .. never a definite cure or fix lol im now seeing if I can do this replacement by myself ..

    • @HVAC_Mechanic

      It is best to test the parts first before replacing them. Here is a link to a video about all the components and how to test them. th-cam.com/video/C5s3Rx3wjD0/w-d-xo.html

    I have an 07 Yukon, started noticing strong gas fumes, sometimes acting up when cranking after it’s been ran, then it’s an absolute nightmare to put gas in it. Takes forever. First thing I did was change the purge valve, then replaced charcoal canister, and blew out the lines. As my luck would have it, trying to put gas it in is still a a pain. At first the fumes went away, after driving it a few times, they are back and it still acts up after a warm start. HELP!!!!! I am going insane!!!!! I don’t think this really matters, but my Yukon is cammed and tuned etc, surely that has zero to do with my issue/issues. ANY help or recommendations would be greatly appreciated!

    • @HVAC_Mechanic
      @HVAC_Mechanic  2 หลายเดือนก่อน

      That is a common system of a bad vent valve. I believe the vent valve is separate from the charcoal canister in that year of Yukon. It may also be the wiring going to the vent valve. It all needs to be tested and diagnosed to know the issue.

      Many people claim it without ever experiencing it. In fact this question is often if not, always asked by somebody who doesn’t have that experience, but its just a clanging gong in the town hall, a.k.a. poser!!
