Function
Each time a tooth passes the Camshaft
Position Sensor G40, a Hall-effect voltage
is induced and transmitted to the Diesel
Direct Fuel Injection Engine Control
Module J248.
Because the teeth are spaced at different
distances apart, the induced voltage occurs
at different time intervals.
From this, the Diesel Direct Fuel Injection
Engine Control Module J248 determines
the relative positions of the cylinders and
uses this information to control the
solenoid valves for pump/injectors.
Refer to “Quick-Start Function” (page 34).
