PURPOSE:To observe the anomaly of each injector by detecting each operation state of a plurality of injectors and detecting the presence of a nontuned injector from the operation state and lighting-up a lamp when a nontuned injector exists. CONSTITUTION:A plurality of injectors 1-4 are controlled by an EGI controller 5, and infection and stop are repeated at a same time. In this case, the operation state (ON/OFF) of each injector 1-4 is detected by an injector operation-state detecting circuit 6. While, a nontuning detecting circuit 7 receives the signal A-D of each injector 1-4 and judges the presence of nonpresence of the nontuned injector. When a nontuned injector exists, a nontuning function is set 1, and a driver 8 is driven to light-up a warning lamp 9, and the presence of the nontuned injector is informed. Thus, anomaly of each injector 1-4 is observed.
