Code P0440 Evap Emission Ctll Malfunction

My 2000 Saturn 1.9L sohc SL shows code P0440 Evaporative Emission Control System Malfunction. The car has about 102k miles with no other major symptoms.

Any suggestions as to where I might look? My mechanic abilities are modest at best.

Thanks

Your Evap system is where you fuel vapors are stored until they are used. A code like that could be caused by a leak somewhere. I dont know where its located at in your car but check the hoses and use a vacuum pump if you have one to see if its working right.

Thanks for the info. I did not know what purpose the evap system had until now. My mechanic skills aren't great, but I can look for cracked hoses and/or a leak.

a loose gas cap is the most common cause of a P0440

Well, the gas cap cover was closed, but the gas cap was completely unscrewed. If that permanently clears the code that will be the simplest fix I have ever had.

thanks very much.
