P0441 (M) Evap Purge Flow Monitor Insufficient or excessive vapor flow detected during evaporative emission system operation. Could be as simple the gas cap not sealing properly.... or it could be one of the many vacuum hoses connecting various components of the evap system that is damaged and leaking. You can visually inspect the hoses, look for cracks or hoses that fallen off completely. Cracks can sometimes be very difficult to see. You can test the gas cap by putting petroleum jelly on the gasket and re-tightening. Clear the code an see if it returns, make sure you have enough gas to last a few days so you don't have to touch the cap.
