ABSTRACT:
The basic fuel injection amount determined in accordance with the rpm and the amount of air drawn into an engine is corrected by first, second and third compensation amounts determined in accordance with the engine operating conditions. The second compensation amount is varied by a predetermined value in response to the output of an O.sub.2 sensor at intervals of a predetermined time. The third compensation amount is read out from the location of a non-volatile memory addressed in accordance with the engine rpm and the intake air amount, varied by another predetermined value at intervals of another predetermined time in accordance with the value of the second compensation amount and stored again in the location from which it was read out. Before starting the compensation of the fuel injection amount, the particular bit pattern stored in the non-volatile memory is checked so as to self-check the third compensation amount data in the non-volatile memory.
