The construction and operation of the cam posi-
tion sensor is the same as for the in-distributor
type, except for the elimination of the voltage
distribution system from the distributor

This circuit also has two NE pickup coils for the
same purpose
as the circuit in © on the previous

Depending on the engine model, there are
also some Engine ECUs
in which the G-
terminal is grounded through a diode
.
When the diode is included in the circuit, a
reading of approximately
0
.7 V is
obtained
when measuring the voltage between G- an
