This has happenned to me several times,and as recently as yesterday. It has ALWAYS been the gas cap. I was low on fuel (1/4) filled up, but more importantly, I paid attention to how the cap was attached when I did not have the CEL come on, as it can be installed two ways. I am sure now to always install the cap the same way each time, to prevent these nuisance false alarms. Whatever works.
When you change the way you look at things,
the things you look at change.
