My '00 GLE is throwing the P1446 code and when I'm trying to fill up the tank, the pump shuts off every gallon or less.
I've changed the Canister Vent Valve (originally I incorrectly said it was the purge solenoid)($100) because the old one was intermittent when testing it (the valve would work once then not again for like 10 seconds). I drove it for a couple days and then it threw the code again. I've taken the canister down and nothing came out of it but I didn't do much with it. I blew out the water separator and there was foam that came out of it, was that incorrectly done? Could the canister be bad? This is a Texas car, so I'm doubting the filler neck is rusted out (it doesn't look bad).
What else can I check?
Thanks for any help!
EDIT - I replaced the Canister Vent Valve, the one attached to the charcoal canister.
Is the vent control valve the one in the tank? I guess I'd need to drop the tank to check that?
The only problem is here in Dallas to pass inspection there can't be any codes being thrown and I am also trying to sell this car. It might be in my head but I think the gas mileage goes down quite a bit when the light is on, too. Does this run in a "limp" mode when that code is thrown? Or is that just me?
Do you have a way to clear codes yourself? If so, try riding around with the gas cap loose, it may throw another code, but if you can erase it then you don't have to worry. You can determine from this if you gas tank is properly venting/creating vacuum, if the other code goes away.
It seems you may have already replaced the vent valve....if you are throwing a code for it, is it possible you put it in backwards? I'm not familiar with them on this car, so I'm not sure if they can be reversed.
I'm still not sure about the foam coming out of the water separator.
Yeah, I'm working at my family's shop and we're using a snap-on computer scanner. I've reset the code everytime it shows up.
I refueled today and after 2 gallons it squirted gas out everywhere. Slowed the pump down to the lowest and it stopped only once.
Are the "water separator" and the "refueling control valve" the same thing? We use ALLDATA repair software here and it shows those as being different components but they look the same. I might have blown the foam out of the "refueling control valve". The foam was like a deteriorated filter inside the component.
