A lot of times, if the CEL comes on right after you get gas or at least 1 day after you get gas, the best way to clear it is to remove your cap, let it vent for a few seconds, and then firmly tighten it. Next, drive about 10-15 miles and that will help reset the readiness marks in the ECM. If that was the problem, the CEL will go off on its own.
