What does the 3597+2 fault code mean?

[GrahamDella]

3597+2 fault code indicates an engine malfunction. The causes of engine failure are as follows: Fuel supply system failure: The fuel supply system mainly includes the fuel tank, fuel pump, pipelines, fuel filter, carbon canister, carbon canister solenoid valve, fuel pressure regulator, fuel injectors, etc. Poor fuel quality: Fuel quality is the primary factor causing the engine warning light to illuminate. The anti-knock property of gasoline is represented by the octane number. The higher the octane number, the better the anti-knock performance. For example, 97-octane gasoline has an octane number of no less than 97. Leaded gasoline can cause lead poisoning in oxygen sensors. Therefore, poor fuel quality is the main reason for insufficient engine combustion, leading to the illumination of the engine warning light. Abnormal fuel pressure: If the fuel pump's supply pressure does not reach a certain level, it will result in poor atomization of the fuel injectors, thereby affecting the normal operation of the engine.
