A method for preventing an engine stall by a virtual crank signal includes determining stability of the engine by measuring an operating time of the engine, storing a crank signal, with a virtual crank signal storing step, using a crank position sensor while a crank shaft makes one turn if it is determined that the stability of the engine is maintained, determining whether the crank position sensor is out of order, and controlling an engine RPM by the crank signal stored in the virtual crank signal storing step to perform idle driving of a vehicle at the time of a breakdown of the crank position sensor. |
