1. Engine failure: The flashing of the engine failure light may be due to some problems of the engine, such as ignition system failure, fuel supply failure, oxygen sensor failure, etc. These problems may lead to engine performance degradation, increased fuel consumption or excessive emissions.
2. Sensor failure: Engine failure light may also be caused by sensor failure. The engine management system of modern automobile relies on various sensors to monitor the running state and emission of the engine. If a sensor fails, the system may misjudge the state of the engine and light the fault light.
3. Exhaust system problems: Engine failure lights may also be caused by exhaust system problems, such as the failure of exhaust gas treatment system and catalytic converter. These problems may lead to the emission exceeding the standard, causing the fault lamp to light up.
It should be noted that the engine fault light does not necessarily mean that the engine has serious problems. It is suggested to contact professional automobile maintenance technicians for diagnosis and maintenance as soon as possible after the engine fault light is found flashing, so as to ensure the safe and normal operation of the vehicle.
In addition, regular maintenance and inspection of the car is also an important step to prevent engine failure. Keeping the engine clean and replacing the air filter, oil and filter regularly can prolong the service life of the engine and reduce the occurrence of faults.
