When the check engine light illuminates in your Ford Fiesta, it can indicate various issues. Your first course of action should be to promptly pull over to the side of the road to prevent any potential harm to your vehicle. Once you have safely parked, you should use an OBD II scan tool to retrieve the code stored in the ECU that triggered the warning light. The primary reason for the check engine light to activate is often a vacuum leak resulting from a loose gas cap. If the gas cap is not the culprit, you will need to conduct a more thorough investigation to identify any faulty components or parts.

Does this actually mean I should tighten the gas cap at the fueling spot? Sorry if I sound silly for asking that question!
