The embodiment of the invention provides a sensor baffle and a vehicle provided with the sensor baffle. The sensor baffle is arranged on the exhaust side of an engine, the sensor baffle comprises a shell, an installation position used for installing a crankshaft sensor is formed in the shell, an opening used for allowing the crankshaft sensor to be inserted therein is formed in one end of the shell, a connecting part is arranged at the edge of the opening, a limiting block is arranged at the edge of the connecting part, and a heat dissipation channel is formed in the side wall of the shell. According to the technical scheme, the sensor baffle is arranged on the exhaust side of the engine, infrared rays radiated by the engine can be prevented from directly irradiating to the surface of thecrankshaft sensor, the temperature rise, caused by heat radiation, of the crankshaft sensor can be avoided so that the crankshaft sensor can be arranged on the exhaust side of the engine, the positionlimitation of the arrangement of the crankshaft sensor is reduced, and the convenience degree of the arrangement of the crankshaft sensor is improved.
