Engine-Speed/Position Pulse Generator

Check function:
[D] 200 - The engine speed signals can be monitored at starting speed or when the engine is running.
Further tests are possible with the oscilloscope [M] 23/24. Connect terminals at the component connector and crank engine. An AC voltage characteristic curve with positive and negative half waves should appear on the display screen.

Resistance test:
The resistance can be measured directly at the component connector (at the connector strip for injector valves). Refer to schematic for wiring diagram.

Possible cause:
If wire, plug connection or resistance are OK:
Check distance of the pulse generator to the incremental wheel on the vibration damper - 0.15...1.5 mm.
Adjustment at holder -1.0 ± 0.3 mm.
