Filed: 1991-12-13
Abstract: PURPOSE:To securely prevent the wrong detection of the deterioration of a sensor in an engine having air-fuel ratio sensors provided on the upstream and downstream sides of an exhaust catalyst by altering a threshold value for detecting the trouble of an air-fuel ratio detecting device through a sensor trouble detecting means according to the state of deterioration of the catalyst.

The control constant of air-fuel ratio feedback control is corrected on the output of the second air-fuel ratio sensor 13. In a fixed domain, a sensor trouble detecting means is actuated to compare the value of the corrected control constant with threshold value for detecting the deterioration of the first air-fuel ratio sensor, but in this case, the threshold value is altered on a parameter relating to the state of deterioration such as the purification rate of the catalyst 7 or the like to prevent the wrong detection of the deterioration of the sensor.
