Dreaded P0441 Evap Code

[Jack@European_Parts]

You need Google to look at the gas cap o-ring seal?

 

[cschmitz20]

Nope the gas cap looks good.

 

[cschmitz20]

I guess I'll try throwing gas caps at it

 

[Jack@European_Parts]

No.... did you run the LDP 071 test with success?

Could you log the test and post the data at idle please?

 

[cschmitz20]

Yes it passed that test

 

[Jack@European_Parts]

Okay did you try turning the N80 purge valve around and running the 070 test?

 

[cschmitz20]

You mean hooking it up backwards? No havent tried that. What will that do?

 

[cschmitz20]

I'll have to try that.havent seen that suggested yet

 

[Jack@European_Parts]

I did question this already but you now realize you ignored it huh , see what happens when you engage?

 

[cschmitz20]

It's not on backwards

 

[Jack@European_Parts]

And how do you know this is so?

Well there is an arrow on it that needs to point towards the hose.going to the engine at least that's what i was told it's facing the same direction as the one I took off

I guess ill try reversing it. I'm thinking it could the charcoal cannisters based on that there are no leaks. Purge valve seems to be functional as does the leak pump. Gas cap appears good. I'm not sure what else could be and there isn't even a way to test the old charcoal cannister. I say it's that cause that seems my luck it would the most expensive thing to replace and the hardest to get to

Ran test for group 70 with cannisters each way and got the evap not ok each way

Also of note not sure if this would be related but I do remember a couple years ago before the engine code cw up i could routinely smell gas around the car. I honestly thought I had gastank leak but never saw any gas. It did eventually go away and havent had it since but I know it wasn't long after that the engine light started going off.it would stay on and it would go off by itself. Then it would turn back on. It pretty much stays on now unless I turn it off myself. Not sure if it would be related or not but wanted to note.

I believe so don't you because LDP passes and pushes those vapors out through N80 to intake?
Doesn't this just sound like a bad line from tank to n80 or charcoal canister?
If it's cracked all that shit is plastic, did you know harbor freight sells a plastic welder for under 20 bucks which is a glorified soldering iron with assortment of plastic filler rod?

Did you know they also sell a mighty vac tester?

Yea that was my thought. I did run smoke through the evap lines and didn't see anything.but I know you said smoke machines aren't the greatest. It's also quite difficult to even see the hoses that run from front to back as they seem to be tucked up inside the chassis almost not even viewable or a accessable.

 

[cschmitz20]

Is it even possible it could be the charcoal cannisters? I think I'd rather have that then a phantom leak that's buried somewhere

It says to test the evap cannisters in basic settings on the causes page I was sent. What group is that in? Are they referring to the charcoal cannister under the spare tire? Also when I do output tests all the data says is NA. Should there values listed there? If so how do I trigger them? I can hear the part working when I got activate but not sure if there should be some sort of value while testing?;
Pete told me.to post.

Time you RTFB sir.........

I would say unless the car was in a collision, the line is more likely a leak or small intake leak than the canister.
