Monitoring fuel system for internal combustion engine with several fuel delivery units involves functional monitoring of fuel delivery units only in regions in which only one unit is operating
The method involves functional monitoring of the fuel delivery units only in regions in which only one of the fuel delivery units is operating. Each fuel delivery unit can be individually switched on and off depending on definable operating parameters. The lambda control value or actual value is determined and compared with a defined threshold value and a defective lambda value detected if the threshold is exceeded.
