Had this code forever...how the heck do you track the leak down? I tightened my gas cap (its original) reset the codes plenty and checked for obvious cracks. But to be honest I haven't spent much time on it cuz its not the most important thing for me to worry about, I just hate the ck engine light.

 

I'm guessing you have a P0441 code for evaporative emission control system incorrect purge flow? I have had that one on and off for some time also. I can clear it and it it will stay out for a while or come back the next day, it's really random. I have not repaired mine yet, but a very common solution is replacing the leak detection pump.

There are a ton of vids about it, here are two that I found that pretty much explain it.



I haven't replaced it yet as I mentioned, I'm just lazy! Plus, you really shouldn't notice any real issues other than the annoying light. They are not expensive and not hard get to.
