Rpm sensor

RPM SENSOR

This is fitted on the crankcase and “faces” the phonic wheel on the crankshaft.

It is of the inductive type, i.e. it works through the change of the magnetic field generated by the passage of the teeth of the phonic wheel (60-2 teeth).

The injection control unit uses the rpm sensor signal to:

• determine the speed of rotation
• determine the crankshaft angular position.

REMOVAL/REFITTING
