My car just threw code P0447 yesterday. I have tried removing and replacing the gas cap on tight and the code still comes back. Has anyone had any experience with this issue and if so, how did you fix it? Thanks for any help you guys can give me.

 

So, no one has had this problem?

 

Anyone?????

 

Did you ever fix the problem?

 

Vent tube that your gas tank uses to vent gas flow is known for going bad

 

And theres a TSB and extended warranty that Infiniti will only honor after you've forked over $350 for a diagnosis and inspection. Better be real broke before you take it in.

 

That's crazy, the part is only like $60 on amazon.. At least the Purge Valve is.

 

vent valve=/= purge valve...good news is you can get a lower mileage charcoal canister with a vent valve on it on ebay for about 50-60 dollars

 

I’ll just change the valve. not sure how to even take out the whole canister

 

its just a few screws, the pressure sensor connector, and a couple hose clips..(about half of wthe stuff you'd be disconnecting anyways just to change the valve), but either way if the problem is solved its solved doesn't really matter which way you do it, good luck

 

Still not coming out. where exactly are these screws?

 

Did you undo connection to tank and I think there is a bottom clip as well

 

If you are in warranty or just a little over they should cover. I had some out of warranty work similar and my dealer did repairs under goodwill

 

nope it’s a 2009

 

Just replace it it's not expensive
