PROBLEM TO BE SOLVED: To enable it to easily compensate an output deviation in a fuel pressure sensor without measuring the actual pressure value in an accumulator in an accurate manner. SOLUTION: An internal combustion engine equipped with an accumulator fuel injection system is made into an idling state and, after this idle running state is stabilized, a deviation between an indicating injection quantity time of this stable idle running state to be secured on the basis of an output signal of a fuel pressure sensor 7 for fuel pressure detection in an accumulator and a predictive actual injection quantity to be predicted in time of the stable idle running state is found out, and on the basis of this deviation, the compensated value to the fuel pressure sensor 7 is found out, thereby compensating the output deviation of the fuel pressure sensor 7. |
