What Causes the Engine Malfunction Light to Keep Flashing?
2 Answers
The reasons for the engine malfunction light to keep flashing are: 1. Poor quality gasoline that does not meet standards; 2. Oxygen sensor malfunction; 3. Air flow sensor malfunction; 4. A certain component of the engine has failed; 5. Poor engine combustion state; 6. Engine misfiring (cylinder misfire). Solutions: 1. Clean the engine: The car owner should promptly go to a repair shop to clean carbon deposits with a specialized cleaning agent; 2. Use higher-grade gasoline: To maintain the engine in good working condition, using 95 or 98 octane gasoline can resolve the issue of the engine light turning on; 3. Improve fuel quality: Use a good fuel additive to enhance the fuel grade.
With years of experience in car repair, I can say that when the engine fault light keeps flashing, it usually indicates a problem with core components. The most common cause is misfiring, which means the ignition of a certain cylinder fails, such as due to aging spark plugs or damaged ignition coils, resulting in no spark. Fuel system issues can also be the root cause, such as clogged fuel injectors leading to unstable gasoline supply or insufficient fuel pump pressure. Emission control devices like faulty oxygen sensors can also trigger the flashing light. If ignored, the engine may continue to shake, fuel consumption will increase significantly, and in severe cases, it can damage the catalytic converter, causing repair costs to skyrocket several times. I recommend stopping immediately to check, reading the fault codes, and seeking professional diagnosis and repair to avoid greater losses.
