and Answers Already Passed
NB: All answers appear above the respective questions (Answers are above the questions).
Electromagnetic induction
Which term describes the principle used to create high voltage from low voltage?
Both Technicians A and B
Technician A says that platinum tipped spark plugs should never be re-gapped after being used
in a running engine.
Technician B says that spark plugs should not be removed from a hot cylinder head.
Which technician is correct?
True
Some engines that use a gasoline direct injection system also have port injection.
Both Technicians A and B
Technician A says that most fuel injection systems use the PCM to control the pulsing of the
fuel injectors.
Technician B says that most fuel injection systems use the PCM to control the operation of the
fuel pump relay.
Which technician is correct?
The injectors can be noisy, due to high fuel pressure

concern is ________.
False
The fuel pickup tube is part of the filler tube assembly (True or False)
Both Technicians A and B
A fuel pump is being replaced for the third time.
Technician A says that the gasoline could be contaminated.

(True or False)
, Both Technicians A and B
Technician A says that fuel tanks on 1993 and later vehicles use a check ball to prevent
siphoning gasoline through the filler neck. Technician B says that methanol is considered a
poison.
Which technician is correct?
True
A GDI (Gasoline Direct Injection) system can be used to start an engine without the need for a
starter motor. (True or False)
