PROBLEM TO BE SOLVED: To provide an injection control device that can determine an abnormality of a fuel pressure sensor and an abnormality of a fuel pump when an abnormality of fuel pressure is detected.SOLUTION: At least a fuel pump 206 for discharging fuel, an injector 207 for injecting fuel and a fuel pressure sensor 201 for measuring fuel pressure of fuel discharged from the fuel pump are connected to an injection control device 220, and the injection control device controls the fuel pump 206 by using the fuel pressure measured by the fuel pressure sensor 201. The injection control device further includes determination means for determining whether the fuel pressure sensor 201 has an abnormality or the fuel pump 206 has an abnormality by driving the fuel pump 206 in a predetermined pattern when the abnormality of the fuel pressure is detected.SELECTED DRAWING: Figure 1 |
