My check engine light just came on and I checked the code and it said this:

P0441 (M) Evap Purge Flow Monitor Insufficient or excessive vapor flow detected duirng evaporative emission system operation.

I took my 2007 caliber to the dealer. The dealer reset the code and after one day the light is back on again. Does anybody have info on how to fix this. Thanks.

 

Do you 'top off' your gas tank when you fill up? It almost sounds to me like you did it to a very excessive amount, and there's no room left in there for the evaporativeemissionssystem to work properly, hence the check engine light.

 

Nope.
