The invention discloses a data verification and correction method for automobile instrument mileage, belongs to the technical field of automobiles, and aims to solve the problem of data damage in a data storage process caused by abnormal working conditions, reduce the frequency of erasing and writing the same storage address space, prolong the service life of a storage device and improve the reliability of the storage device. The method comprises the following steps that 1, the total mileage is divided into whole kilometer mileage data and non-whole kilometer mileage data in a mileage data segmentation mode, and the whole kilometer mileage data is divided into multiple sets of data to be stored in different address spaces in an electrically erasable programmable read-only memory EEPROM; the total mileage is divided into the whole kilometer mileage data and the non-whole kilometer mileage data, and the abnormal data is corrected in time by utilizing the error correction algorithm, so that the data damage in th
