Deteriorated Gas Cap
The gasoline will evaporate if the gas cap is broken, chipped, or otherwise damaged. The powertrain control module (PCM) will be notified of this problem by the EVAP system sensors. Now the dashboard warning telling you to check the gasoline cap will be triggered by the PCM or car computer.
