I've done a search for this code on the site and it seems to have something to do with the venting of fuel gases. I have no idea where the parts are for this or which ones to replace or test or inspect.

 

Any direction would be much appreciated.

Well that would be the evap system. The evap control valve is malfunctioining.

So where is the evap control valve and what exactly does it do?

the entire evap system helps remove vapors in fuel system...i believe the control/purge valve opens and closes the system as necessacary....there is a chance i am slightly wrong though.......

Check and see if your Fuel Fill cap is on tight, and sealing, this is the most common and first place to check when you get an evap system problem.

I was doing some fuel system maintenance a couple weeks ago and when I added seafoam to the tank, more of it ended up on the ground than in the tank. Is there a potential relation between these two events?

Depends on why and how it wound up on the ground. For example, if it went down the filler neck without backing up, you might have a rusted through fuel filler tube.

I suppose I better find some time to get in there and check it out.
