1. NOTE! Cut the current with the main switch.
2. Connect adapter cable 88890016 and the mea-
surebox 9998699 with the engine connector. Do
not connect the MDI.
3. Use multimeter 9812519 to measure resistance.
Measurement points Nominal value
17 - 18 R ≈ 0.9 kΩ
4. Remove the sensor from the flywheel casing.
Check that the sensor has no external damage
and that no metal chips are stuck on the sensor.
5. Use multimeter 9812519 for a AC voltage mea-
surement.
6. Move a metal object rapidly back and forwards not
