★ Top Answer
The check engine light in a 2012 Ford Fiesta alerts you to any issues or malfunctions with your vehicle's parts or systems. It could indicate simple problems like a loose gas cap or a need for engine oil, or it could signal more serious issues like damaged spark plugs, wires, or coils, thermostat problems, a faulty catalytic converter, a malfunctioning mass airflow sensor, a faulty oxygen sensor, or a bad exhaust gas recirculation valve. If the check engine light is flashing instead of remaining steady, it means the engine misfired or a cylinder may not be functioning properly. A flashing check engine light is a more severe indication than a steady one and can lead to significant repair costs.
