The embodiment of the invention discloses an engine control method and device and a vehicle. The control method comprises the steps that it is determined that a first water temperature sensor breaks down; the electronic thermostat is controlled to reach the maximum lift, and the fan is controlled to reach the maximum rotating speed; the fault duration of the first water temperature sensor is obtained; determining a corresponding temperature control value according to the fault duration; and executing a corresponding processing scheme according to the temperature control value. According to the control method in the embodiment, on one hand, after it is determined that the first water temperature sensor breaks down, the electronic thermostat can be controlled to reach the maximum lift in time, the fan is controlled to reach the maximum rotating speed, the temperature of engine cooling liquid is controlled not to exceed the temperature, and normal operation of an engine is ensured; and on the other hand, the cor
