ABSTRACT:
A fuel injection control system for an internal combustion engine having means for limiting a fuel amount to be supplied to the engine according to an output of an air flow sensor to a predetermined upper limit value, and means for correcting the intake air flow rate by the output of the air flow sensor when the opening of an intake air throttle valve is opened at a predetermined value, thereby limiting the output of the sensor to the predetermined upper limit value in case that the output of the sensor increases larger than the actual value and correcting the air density if different from a reference by the correcting means.
