In this video I have a look at a 2005 Chevy 1500 that came in with a P0449 EVAP Code. This is a pretty common failure in our neck of the woods and a really easy fix. - Enjoy!

    Not even close to the repair on my truck. Mine was the square style, smashed into a spot from GM that seems really stupid. 2003-05 EXT CAB, Z71, 6.5' bed models… I believe, someone correct me if I'm wrong. I looked into replumbing everything, to make the repair easy, and the issue becomes the wiring. Also, the "repair kit" available at most auto parts stores cost nearly $200. The bulletin from Delco on this issue calls to re-plumb it with heater hose. I bought 5/8 gas line hose instead, because, its gonna have some fuel vapor in it. Never used it, due to above electrical hassles. I was able to fish everything back into the factory spots, only spending 40 bucks for the evap vent solenoid itself… and the $$ for the hose b/c O'Reillys counter guy was a little dim. Oh well. The CEL went off after driving the truck for a few miles. Runs like a champ! – 2003 Silverado LS ext cab, 5.3L, Mfg at the Canadian plant, 6.5' bed, z71 package, towing package, driven in the rust belt. Note: The solenoid I took out looked like a little explosion went off inside it!!!

    Will this valve stuck shut cause the car to not fill up with gas properly? It has a p0446 and a p0445 code

  12. Avataaar/Circle Created with python_avatars Bill Bird says:

    Would be nice to show if any wiring differences

    Has anyone ever had this issue and also had to replace the ECM or whatever it's called? Years ago I had an '06 Sierra 1500, 5.3 and had this issue. Along with paying $300ish for the valve, the dealership wanted me to pay $700 to replace the computer. Thankfully I had warranty that covered it.

    Fairly dumb idea to design a "Pickup Truck" this is usually the type of vehicle most prone to drive on dirt roads use a Evap Filter system that can't take the trail it should ! Regardless of the age of the vehicle, this EPA required hardware needs to be better designed to last !

    Wait a minute! Is that tobacco in your bottom lip or just a weird reflection in the magic screen thingy you conjure with to do you mechanic voodoo stuff? Mrs. O is going to have a fit when she reads this. Hehehe……..

  22. Avataaar/Circle Created with python_avatars Thanh-Danh Ho says:

    Regarding your issue with the auto ranging min/max values. If you wanted static values, then you would have to set your min/max each time you used it. And if you didn't set it correctly, then when you reached the limits the trend would flatline which could be mistaken as well. It's tough for the programmer especially when the trend area is small like shown.

    I have same problem in a 04 Silverado thanks for walking me through it when the weather gets better I'll change it

  26. Avataaar/Circle Created with python_avatars real life repair says:

    Next time you do one of these try moving it beside the transfer case,just lengthen the wires and use a piece of heater hose,this gets it away from road crap,they last alot longer,I've done quite a few that way and it seems to work good

  27. Avataaar/Circle Created with python_avatars Tom Dewey says:

    That truck looks like a rusty rotted mess underneath. It makes my 1999 Silverado 1500 look mint in comparison ( and it lives in New Hampshire).
