I have had a check engine light on for some time now, So i had Auto Zone check it the other day and it says P0440 - Evap Emissions Control System Malfunction

Anyone get this code and have it resolved ?

I was going to start with buying a new gas cap and see if that works first, Any other suggestions ?

 

I would check the cap to make sure that it is on tight
I would also check the chart under the hood and follow the vacuum hoses to make sure there are no leaks

 

gas cap is most common, and its cheap to get another one, give'er a try

 

I am going to buy a new cap today, If it is the problem and i have auto zone clear the check engine light, does it just turn of the light or does it clear the code ?

Reason i ask is i have a inspection coming up next month and i dont want it to fail because the code is still in there. ( Assuming it fixes the problem)

 

Ok i put a new gas cap on , Do i have to have Auto Zone clear the code , Or will it go off on its own ? Thanks.

 

It should go out on its own

 

if it doesnt go out then try clearing it, then if it come's back on then you know its something else
