What's the reason for the car's anti-theft system malfunction preventing ignition?

[JourneyRose]

The reason the car's anti-theft system malfunction prevents ignition is likely due to a fault in the vehicle's anti-theft system. Below are the potential causes of this malfunction: Electrical faults in the engine: These faults may include damage to certain sensors, such as the air flow meter, throttle idle motor, intake pressure sensor, oxygen sensor, etc. Additionally, they may involve control units or actuators, like the engine control unit (ECU), ignition control unit, fuel pump, or camshaft adjustment solenoid valve. Mechanical faults in the engine: These can arise from changes in fuel quality, such as using fuel with excessive additives, or from carbon buildup covering the intake tract, throttle, or spark plugs. Air leaks in the intake tract below standard values can also cause corresponding faults. When an engine electronic control system fault occurs, if only the yellow warning light is illuminated, you may continue driving but should promptly visit a repair facility for inspection. If the red warning light comes on, you should stop the vehicle immediately and contact a repair facility for assistance.
