Kubota D1803-CR-E4 User Manual

3.18 Crankshaft position sensor
3.18.1 Outline of crankshaft position
sensor
The crankshaft position sensor senses the pulsar hole
on a
flywheel and detects the angular position of the
crankshaft.
3.18.2 Structure of crankshaft position
sensor
The crankshaft position sensor is made up of a magnet
and connector and the like.
(1) Terminal ground
(2) Terminal signal
(3) Terminal 5 V
(4) NE sensor input circuit
3.18.3 Function of crankshaft position
sensor
The crankshaft position sensor senses the pulsar hole
on
a
flywheel and detects the angular position of the
crankshaft.
The flywheel has some pulsar hole missing.
The engine ECU calculates the piston position and
engine speed based on the signal detected.
The crankshaft position sensor is a magnetic resistance
element type sensor.
When the flywheel passes by the sensor part, the
internal magnetic field changes.
AC voltage is generated by the change in magnetic
field and this is rectified and output to the engine ECU.
(1) Pulsar holes
3.18.4 Specification of crankshaft position
sensor
Operating voltage 5 V
Number of pulsar holes at fly-
wheel
56
Output waveform
(1) 56 pulses (6.28 rad (360°)
crank angle)
(2) 5 V
(3) 0 V
NOTE
• Noted as Ne sensor on Diagmaster
