ASE MLR practice Exam Questions withAccurate Answers
a vehicles right front wheel has a growling noise that increases with vehicle
speed. most likely cause is: - -a worn out wheel bearing will cause a growl
that increases with speed.
-White colored exhaust is billowing from the tailpipe of a vehicle. Which of
the following is correct?
A. It has worn piston rings.
B. It has a leaking head gasket.
C. It has worn valve seals.
D. It has a leaking fuel injector. - -Answer B is correct. A leaking head
gasket results in a coolant leak from the jacket into the cylinder producing
white/gray exhaust.
-An automatic transmission's fluid is pink and milky. Technician A says this
is caused by engine overheating. Technician B says the transmission could
have been overfilled and the fluid has become aerated. Who is correct? - -No
one is correct. Neither technician is correct, the ATF is contaminated with
coolant.
-Technician A says fuel filters have an arrow that always points toward the
fuel tank. Technician B says a clogged fuel filter will reduce fuel pressure at
the fuel rail. Who is correct? - -
-. A vehicle with power assist brakes has a hard brake pedal with little
stopping power. Which of these is the MOST likely cause of this condition?
A. The brake booster.
B. The master cylinder.
C. Air in the system.
D. Contaminated brake fluid. - -
-a vehicle pulls to the left only while braking. technician A says this could be
a restricted left break line. technician B says this could be a frozen right
caliper. who is correct? - -it is technician B because a frozen right front
caliper will cause the vehicle to pull to the left when breaking. and if it were
the front break line wit would cause the vehicle to turn right not left. because
the right front break has more stopping power.
-a vehicles air conditioner blows cold air while driving at normal speeds, but
warm while at a stop lights. the LEAST likely cause of this condition is: - -a
, frozen expansion valve: this is the least likely type question. once the
expansion valve freezes, the air conditioner would have poor performance at
all speeds
-a technician runs a scan and receives a fault code indicating a problem in
the MAF sensor circuit. technician A says this could be caused by a loose wire
or an intermittent open. technician B says this could be caused by a faulty
MAF sensor. who is correct? - -Both A and B are correct.
-a vehicle blows blue gray exhaust from its tailpipe only when first started in
the morning. the MOST likely cause of this condition is: - -a leaking valve
seal will cause oil to leak into the cylinder's chamber over time, usually
overnight, resulting in blue gray exhaust at first start.
-the headlights get brighter as the engine is revved. Technician A says this
is caused by a high capacity battery. Technician B says this is caused by a
faulty voltage regulator. who is correct? - -Technician B is correct. at the
heart of the charging system is the alternator, if the alternator outputs
excessive or high charging voltage, check voltage regulation; electrical
components, and electronics will be affected. and because the battery is
primarily used to start up the engine.
-A vehicle with a power rack and pinion steering system is binding only while
turning corners. which of these are least likely to cause this condition? - -
worn rack bushings can cause a vehicle to wander. this is a least likely type
question.

the following statements are true except...
A) raise the front tires in the air.
B) turn the wheel from stop to stop to bleed air from the system.
c)flush with fresh power steering fluid.
D) hold the wheel for at least 10 seconds at each steering stop. - -D) don't
hold the wheel against the steering stops for more than 5 seconds. doing so
increases system pressure so high it can rupture hoses and damage system
components.
-A red colored fluid is seen leaking between the transmission and the
engine. Technician A says this is caused by a leaking rear main seal.
technician B says this is caused by a leaking transmission pump seal. who is
correct. - -technician B is correct. a leaking oil pump seal will result in
automatic transmission fluid leaking between the engine and transmission
bell housing. and transmission fluid is red and oil is tan or brown colored.
