ABSTRACT:
A feedback control system for controlling the fuel/air ratio of an engine. The system employs a fuel/air ratio or combustion condition sensor and includes a checking system for checking if the sensor is providing reliable data. This is determined by determining whether the output of the sensor changes when an adjustment in the amount of fuel supplied is made. If the sensor check indicates unreliable signals, then the system operates on an open control.
