Crank Angle Sensor Unit
1. General
The crank angle sensor unit is installed on the supply unit drive (7) at the driving end
(see Fig. 1).
There are two crank angle systems that monitor the teeth on the intermediate wheel.
The two sets of proximity sensors (2, 3 and 4, 5) operate independently to sense the
teeth on the intermediate wheel (1).
Two more proximity sensors (10) and (11) are used to find the crank angle marks for
TDC and BDC on the flywheel (8) (see Fig. 2).
All proximity sensors are connected to each CCM−20 (see 4002−1 Engine Speed and
Crank Angle Sensor, paragraph 3.5).
