My wife's car is throwing the above p0441 code. I replaced the purge valve, which was bad, so it's narrowed down to the charcoal canister or the vent solenoid. Now, my wife was in the habit of "topping off" when she filled the gas tank, to the point where she could see the gas practically coming out of the fill hole. I've heard that this could ruin the charcoal canister. I guess my question is what my course of action should be. Is tehre any way to know if the problem is the charcoal canister or the vent solenoid? I can buy a vent solenoid for $20-something, but a charcoal canister would be $130 or so.
have the same problem?
