ABSTRACT:
An air/ratio control system and method for an internal combustion engine coupled to a fuel vapor recovery system simultaneously maps a difference between a desired air/fuel ratio and a measured air/fuel ratio to fueling errors and a purge vapor flow. This system and method maximizes the ability to purge the vapor recovery system while maintaining the ability to diagnose fuel errors.
