PURPOSE:To avoid the fuel cut under acceleration of engine by releasing stoppage of fuel supply to the engine upon detection of abnormality of a throttle valve full-close position detecting means through specific method. CONSTITUTION:Upon provision of a full-close signal from a vlave full-close position detecting means 4, an electronic control unit 5 will decide whether the engine rotation is at the specific level or not. If the throttle valve opening signal level is higher than predetermined level and predetermined time has elapsed, an accelerator switch 18 will decide it to be abnormal. If the opening of the throttle valve 6 is decided to be higher than predetermined level or the absolute pressure signal is higher than predetermined level, it is decided not to be the operating region for performing fuel cut to execute fuel feed control. In such a manner, fuel cut can be prevented under acceleration of engine. |
