t2 = Second Segment
t3 = Third Segment
t4 = Fourth Segment
d = Period for one crankshaft rotation
The crankshaft position is recognized from the voltage signals which are produced. The segment front edge generates a negative voltage signal.
The segment rear edge generates a positive voltage signal. Engine speed is determined by measuring the period (d) which is equal to one
crankshaft revolution.
SIGNAL
This AC voltage signal is used by the EZL/AKR control module and transmitted via the controller area network (CAN) to the LH control module.
