VGTCV (Variable Geometry
Turbocharger Control Valve)
OPEN
• The VGTCV (Variable Geometry
Turbocharger Control Valve) is a duty cycle
controlled valve that directs oil flow to the
piston that controls the vanes in the
turbocharger.
• The valve controls pressure to both the open
and close side of the piston.
• If the valve is disconnected the turbocharger
vanes will remain in a open state.

FICM (Fuel Injection Control Module)
• The FICM (Fuel Injection Control Module)
receives Information from the PCM (like
volume of fuel desired, RPM, EOT, ICP and
others) and uses those signals to calculate
injector start of injection and duration.
• After calculating injector fuel delivery time
the IDM sends a 48 volt 20 amp pulse to the
correct injector so that the correct amount of
fuel will be delivered to the cylinder at the
correct time.
