Abstract
A method and device for testing a fuel metering system. A control unit checks the injector contacts during the initialization phase prior to starting up the fuel metering system. For the test, the injectors are activated by the control unit, and the current values and/or voltage values are evaluated to detect errors. The control unit controls the fuel metering process during operation.
