ABSTRACT:
A method and system for monitoring fuel delivery to an internal combustion engine having a first and second mode of operation and controlling the engine accordingly. An oxygen content of exhaust gas emitted from the engine is sensed and a corresponding oxygen content signal is generated. Air fuel ratio correction data is determined based on the oxygen content signal. If the engine is operating in the first mode, the air fuel ratio correction data is compared to a first set of predetermined air fuel ratio correction thresholds and a first failure signal is generated based on the comparison between the air fuel ratio correction data and the first set of predetermined air fuel ratio correction thresholds. If the engine is operating in the second mode, the air fuel ratio correction data is compared to a second set of predetermined air fuel ratio correction thresholds and a second failure signal is generated based on the comparison between the air fuel ratio correction data and the second set of predetermined air fuel ratio correction thresholds. The engine is controlled based on the first and second failure signals.
