I have a dtc P0441 Evap Purge Flow Monitor. I cleared it once, but after a couple weeks it came back. I have never overfilled the tank, actually I havent even filled it up full since I got it. ha.
Im just wondering what it might be, I'm assuming it isnt anything serious?
How can I troubleshoot for a source of the problem?

thanks

 

anyone?? is this a dumb question? i didnt really find anything in the search... the ones i did find had no replies.
had planned on checking into it tomorrow....
