Rail pressure sensor verification method, device and equipment

The invention discloses a rail pressure sensor verification method, device and equipment. The method comprises the steps that firstly, the maximum oil supply amount of a flow metering unit before engine synchronization is obtained; the first standard rail pressure rising amount caused by oil supply each time is calculated based on the maximum oil supply amount; on the basis of the obtained first standard rail pressure rise amount, the total second standard rail pressure rise amount in the process before engine synchronization is obtained through calculation; a first actual rail pressure variable quantity and a second actual rail pressure variable quantity are obtained through calculation according to actual rail pressure values collected by a rail pressure sensor in real time; and generating a corresponding fault signal based on a comparison result of the first standard rail pressure rise amount and the first actual rail pressure change amount and a comparison result of the second standard rail pressure rise
