ASE Test Prep QUESTIONS ANDANSWERS WITH VERIFIED SOLUTIONS
100% CORRECT!!!
Technician A says that when pressure testing a radiator cap, a special adapter is
needed. Technician B says the best way to check thermostat operation is while it is
in the engine. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔The correct answer is A. Test the radiator cap
with the cooling system tester's radiator cap adapter. The thermostat can most
effectively be rested by removing it from the vehicle, and submerging it in coolant
heater about l 5°]: (8°C) above the normal thermostat opening temperature.
2. A technician Is checking resistance In an engine's spark plug wires using an
ohmmeter. A general rule Is to replace a wire if resistance is over:
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔2. The correct answer is B. A general rule is to
replace the wire if the resistance is over 30,000 ohms. The resistance of suspect
wires can be checked using an ohmmeter. To check resistance, disconnect the
spark plug end and coil end of one spark plug wire. Connect an ohmmeter lead to
each end of the spark plug wire's terminals.
,3. Technician A says that in an ignition system, the voltage supplied to the coil
during starting is battery voltage. Technician B says the coil uses electromagnetic
induction to create high voltage. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔3.The correct answer is C, both technicians.
Battery voltage supplies the primary side of the ignition coil with 12 volt cs. The
coil uses electromagnetic induction to create high voltage. When the voltage is
reduced on the primary side of the coil, the collapsing magnetic field induces a
much higher voltage in the secondary side and sends it through the secondary
system in the spark plugs.
A Front Wheel Drive (FWD) vehicle with an automatic transaxle has excessive
vibration. Technician A says that the vibration could be caused by worn
engine/transaxle mounts. Technician B says that the vibration could be caused by a
misaligned engine/ transaxle subframe. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔4.The correct answer is C, both technicians.
Worn engine and transaxle mounts can cause vibration, but driveline vibration can
also be caused by an engine transaxle subframe that is damaged or not properly
positioned and secured to the vehicle.
5. A technician suspects that a faulty camshaft sensor causes a driveability
complaint. The sensor is equipped with a threewire connector. What type of sensor
is this?
, A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔5.The correct answer is A. Hall effect switches
are equipped with a threewire connector; magnetic reluctance types are equipped
with a twowire connector.
6. All of the following can cause a problem in the Hydroboost system EXCEPT:
A. loose power steering pump belt
B. leaking power steering hoses
C. low power steering pump pressure
D. leaking check valve - ANSWER✔✔6.The correct answer is D. A vacuum check
valve is used on a vacuum power booster. The Hydroboost system operates by
using power steering pump fluid pressure rather than vacuum, so all of the other
choices would apply.
7. Technician A: says that if a wire is getting too hot, it's a sign of
higherthannormal current flowing through. Technician B says the wire would heat
up if some of the individual strands are broken Inside the wire insulation. Who is
right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER✔✔7.The correct answer is C, both technicians. A
hot electrical wire means more electrons are trying to flow through it than the wire
