ABSTRACT:
A feedback control system for an internal combustion engine that employs a combustion condition sensor for feedback control. The output of the sensor is checked periodically, either by changing the fuel-air ratio and determining if the output changes or by seeing if the output is constant during periods of constant running conditions; and if the sensor is determined to be inaccurate, another control method is employed.
