The invention relates to the technical field of automobile fuel tank theft prevention, in particular to a fuel tank theft prevention system, a fuel tank theft prevention method and a fuel tank cap. The upper-layer structure of the cover body is provided with an accommodating cavity for accommodating the circuit board and the first detection module; the cover body lower layer structure is provided with an elastic sheet and a second detection module; the oil tank cover is tightly connected to an oil tank opening of the oil tank through the elastic piece. The sensor and the circuit are arranged in the fuel tank cover, system modification cost is avoided, and implementation is easy; the liquid level is directly measured through the ultrasonic sensor; multiple sensors are fused to monitor the fuel tank cap (upper and lower layers) and the fuel level state; the vehicle state is judged through the inertial sensor, other parts of the system are kept dormant in the driving state, system power consumption is reduced, and the service life of a battery is prolonged; the used sensors are all products which are adopted in a large scale in the fields of consumption and generic industry. Compared with the current mainstream scheme, the cost can be saved by 50-80%.
