The invention relates to a method for monitoring the execution of a program in a microcomputer of an electronic device, especially a sensor circuit for motor vehicles. According to the inventive method, the program processes input data and produces output data, copies a program in addition to the program which is executed, said copy being stored in an address area in the micro-computer other than the program, using the input data provided for the program. The output data of the copy is compared to the data of the program and an error message is produced if the programs are not consistent.
