As a tech for 22 years don't try to diagnose this problem yourself there may be a concern with any one of the emission systems if you clear the code the tech won't be able to find the problem until it occurs again!! with only 16,000 k it should still be under warranty

 

That had happened to me also "gas cap" I thought I had it tight but it wasn't mine clicks then stops clicking then clicks again meaning its tight ( I have to go beyond the first few clicks to tighten).

 

You could also try hitting the light with a hammer, that'll fix it

 

i have check my gas cap and it seems fine and tight it again, i'll bring it to Honda tomorrow after work...
