I have a 99 Civic LX.. 107k

This morning it threw the CEL. I checked it and this is what is showed.
This reader shows one line at a time here is EXACTLY what was displayed. The car appears to be running just fine but I wanted to get some feedback from the experts here since I'm pretty much a newb when it comes to anything aside from general maintenance.
TIA!

Check whether the seal of your gas cap is bad. If so, replace and clear CEL -- remove 7.5A BACKUP fuse from under-hood fuse/relay box for 10 seconds and reinsert. If CEL does not return, then problem is fixed.

By the way, it is also possible that the cap was not screwed down tightly after the last fill up.

 

Now that I think about it... This is an aftermarket gas cap. My wife drove off with the cap on top of the car after getting gas a couple years back. I wonder if this has anything to do with it. I will look at the cap and see if the seal is screwed up or something. BTW would you happen to know what all the other info in the OBDII reader means...

For the Civic, the code indicates an EVAP system malfunction:
