Injector Valves

Injector Valves:

Check electrical function:

•D• 300 - In this case, the fuel injector valves are driven with a frequency of 10 Hz. The pulse period is 1 ms in order to avoid fuel being injected. Activation can be felt with the hand. The pulses can be tested with the multimeter at the injector valve connector.

Resistance test:

The resistance of an injector valve must be measured directly at the component. Only the entire injector valve group (e.g. 3 valves on 6-cylinder engine) can be measured from the DME control unit connector. For technical data, see Technical Data.
