CAPONORD 1200
Neutral sensor
Function
It tells the gear position to the control unit, from the
1st gear to the 6th gear, and if the gear is neutral
or riding.
Operation / Operating principle
The sensor has 2 circuits: one to indicate the en-
gaged gear, whose resistance varies according to
the gear engaged: in this way, the injection ECU,
according to detected electric voltage, identifies
the engaged gear and sends the information via
CAN to the instrument panel; the other indicates
neutral gear, whose voltage is taken to zero if in
neutral position.
