Abstract
Herein disclosed is a method of processing a malfunction of an accelerator pedal sensor of an automobile. An output voltage is outputted according to changes in a resistance depending upon depression of an accelerator pedal. A malfunction of the accelerator pedal sensor is shot to process and determine an acceleration value for controlling the run of the automobile in accordance with said output voltage. The acceleration value is set at a predetermined value in accordance with the malfunction of either of an idle switch for generating a signal indicating the idle position of the accelerator pedal and a wide-open switch for generating a signal indicating the wide open position of the accelerator pedal when the malfunction of the accelerator pedal sensor is judged. This judgement is conducted by detecting a plurality of times that said output voltage is outside of the predetermined voltage range. The acceleration value is set at a predetermined minimum value, when the idle switch is in a normal state, at a predetermined relatively high value, when the wide-open switch is in a normal state, and at a predetermined relative low value when both the two switches are troubled.
