> a P0440 means there is an evap leak… .loose gas cap, leaking line, ect… this is not a visiable leak, its more of a vapor leak. Now also has a P0441 for purge valve flow, i would be looking to see if your purge valve is opening and closing.  
> the purge valve should be up on or near the the engine. a vent valve will be more near the gas tank. hope this helps.

thanks man,we will be looking for this till he gets back,we want to fix it for him
