Description And Operation
The rpm sensor is Hall-effect type (in the Euro 5 version it is inductive type), which means that its operation is determined by magnetic field changes generated by the toothed wheel's teeth (60-2 teeth). It is used by the Engine Management Node to:
- Determine the rotational speed of the crankshaft
- Determine the angular position of the crankshaft
The engine rpm sensor is fitted to the block and faces the toothed wheel on the crankshaft.
