Proximity Sensor − Replace
1. General
The crank angle sensor (CAS) unit (Fig. 1) is installed on the supply unit drive at the
driving end. The CAS has four proximity sensors (ST5131−34C). There are two crank
angle systems (for redundancy) that monitor the teeth on the intermediate wheel (1).
The holder (2) is installed with screws to the cover (3) on the drive column.
Two more proximity sensors (ZS5123−34C) are used to find the crank angle marks on
the flywheel (4) for TDC and BDC.
