Technician A says that without power to the VGT actuator, Tech A
the actuator could potentially provide a lot of boost
pressure because the vanes are as much as 95% closed.
Technician B says that the turbocharger will not provide
very much boost because the vanes default to an open
position. Who is correct?
Technician B
Neither Technician A nor Technician B
Both Technician A and Technician B
Technician A
Technician A says that the operation of the VGT actuator's Neither
electric motor is inspected during a bounce test.
Technician B says that the motor needs to be removed
and checked with an ohmmeter to determine whether it
is faulty. Who is correct?

Technician A says that a late-model engine equipped Tech A
with a compression release brake and a VGT will close
the vanes to increase intake boost and exhaust back
pressure during braking. Technician B says that the vanes
will open to reduce intake airflow during engine braking.
Who is correct?
Technician B
Both Technician A and Technician B
Neither Technician A nor Technician B
Technician A
Technician A says that the turbocharger speed sensor is Both
used to sense and help prevent a turbocharger
overspeed condition. Technician B says that the speed
sensor is used by the HD-OBD system to detect faults
with the turbocharger. Who is correct?

Technician A says that VGT engines can electronically Both
vary turbocharger boost pressure. Technician B says that
boost pressure from VGTs is typically higher than boost
pressure from fixed geometry turbochargers. Who is
correct?
Technician B
Both Technician A and Technician B
Neither Technician A nor Technician B
Technician A
Consider a series-sequential (parallel) turbocharging Low-speed, low-load operation
arrangement that uses two separate turbochargers.
Under what conditions will the high-pressure
turbocharger provide maximum boost pressure?
High-speed, low-load operation
Any low-load operation
High-speed, high-load operation
Low-speed, low-load operation
