The invention provides a sensor diagnosis method, a storage medium and a vehicle, and belongs to the technical field of vehicles, and the method comprises the steps: obtaining a motor state of a target motor; determining a target diagnosis strategy for the target temperature sensor based on the motor state; obtaining inverter temperature information, collected by a target temperature sensor, of the target motor; and diagnosing the inverter temperature information based on the target diagnosis strategy to obtain a diagnosis result for the target temperature sensor. According to the embodiment of the invention, the appropriate target diagnosis strategy can be dynamically matched according to the motor state of the target motor, and then the target temperature sensor is diagnosed in a targeted manner, so that the abnormality diagnosis can be simply and efficiently carried out on the target temperature sensor on the premise of not increasing the hardware cost, the scheme is convenient to deploy and implement, and the diagnosis efficiency is improved. The method does not cause a large computing power burden to the controller, and can also ensure the accuracy of diagnosis.
