Will the engine fault code disappear by itself?

[VonAnastasia]

It will not disappear by itself and can only be cleared using a fault diagnostic tool. The engine fault light is an issue that no car owner should ignore, as it directly relates to engine lifespan and driving safety. Reasons for the engine fault light to illuminate: Carbon deposits on spark plugs: After some time of use, the engine accumulates carbon deposits, which can cause engine damage, difficulty starting, poor acceleration, excessive engine noise, and other issues. The accumulated heat can lead to irregular engine ignition, resulting in engine knocking. In such cases, the engine fault light will illuminate. Fuel quality issues: Poor or substandard fuel quality. Some car owners may notice the engine fault light turning on immediately after refueling, which is usually caused by filling up with low-quality fuel at non-standard gas stations.
