ABSTRACT:
According to the device of the invention, measured values (V.sub.0 ', V') of an output V.sub.A of an opening sensor at two adjusted levels of throttle openings in both idling state and fast idling state and their ideal values (V.sub.0, V) are used. The value V.sub.0 ' in the idling state is subtracted from the output V.sub.A in a driving condition, (V.sub.A -V.sub.0 '), which is then multiplied by the ratio of ideal variation characteristics of the sensor output for a change of the throttle opening to those in the throttle valve product used, {(V-V.sub.0)/(V'-V.sub.0 ')}, to produce a correction signal T.sub.A matching the individual difference. Further, a reference value subtracted from the output V.sub.A in a driving condition is set as T.sub.AMIN which varies with the output V.sub.A, taking the difference of variation characteristics of the sensor output from ideal characteristics into account.
