If your vehicle uses a removable fuel cap, check that it is fitted correctly according to the manual. A loose or damaged cap can be relevant to a fuel-system warning, but the light alone does not establish the cause.
Capless systems have different checks, and a warning may not disappear immediately after a correction. Avoid repeatedly clearing it. Let 12th Street Auto Care Center know whether the message followed refueling and whether the cap or filler opening appears damaged.
