Chevy Truck: P0449 EVAP Vent Valve Performance
video description
I have a 2008 f-250 and I'm hoping she'll last this winter. When I try to work on her, she showers me with rust flakes, it's like somebody dumping a bowl of cornflakes on me. The rust seems to accelerate, proportionate to the square of her age, until there's nothing left to work with. In the spring, we'll have to send her back to China (she's 50 % Chinese, at least) and they will make toasters or washing machines out of her.

I have been using a fuel injector noid light to connect to the vent solenoid connector to easily check for a circuit problem. Nice and convenient and plugs right in. It also works on quite a few other solenoids such as Ford IWE solenoids. I have not used that version of OTC scanner but on other units I believe you can override the graph min and Max by clicking the three dots on the top right of the graph. Good videos, thanks

Have to laugh Eric, when you said the truck is almost going to Chevy heaven, in upstate New York due to rust I just looked on the major New Zealand trading website TradeMe, there are three 2005ish Chevrolet trucks for sale all around 50, 000 NZ. That's still about 33000 US, probably more than it was new over there. Us New Zealanders have a love affair with american Iron, but man o man do we pay way too much for it!

I found if I do not over fill my 2006 Chevy truck fuel tank, the vent valve does not go bad. When filling the tank, STOP when the pump clicks off. Do not add more fuel. I replaced it twice in the first 6 years. Now it's been 6 years since I've had to replace the vent valve, since I stopped over filling the tank. And I'm in Alabama, it's not just a New York problem.

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.

Scan tool options. In the upper right hand corner of the graph displays there are three little dots stacked vertically. When I see those on my cell phone, they mean that pressing them gives me a menu. I was wondering if you press them could you change the graphing options? Thanks for taking us all along. fun watching a pro work.

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.

I still can't wrap my mind around the fact that it's inevitable your vehicle will rust away. literally, over there. I have a truck that's been in the family for about 30 years. no rust. The only thing here in California is the sun will just bake the clear coat off and crack the dash to bits

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!
