Especially advantageous it is when the rail pressure and / or the fuel quantity and / or the engine speed is limited to a smaller value than in normal operation. Furthermore, it is advantageous if the driver by a warning lamp on the emergency operation is informed so that he visits a workshop. Furthermore, the pump error is preferably in a Error memory entered. This simplifies the Fault diagnosis.

In this case, must by an external logic in the area of the controller 160 be excluded that the test when switched off Element shutoff valve is performed. The same applies if no Elementabschaltventil is provided. In In these cases, the device only provides a signal indicating that a pump element is not working.

Will one Implausibility before the start or at the start detected, for example, because the rail pressure is not on one expected value increases, the internal combustion engine can not start. The cause of this error is not without More recognizable. Such an error can be on the one hand that is a mistake in the area of high pressure pump or an error has occurred in the area of the pressure regulating valve 135 is. The troubleshooting is therefore partly very consuming.
