COMPLETE 55 QUESTIONS

Question 1: A hydraulic power steering system groans after a hose replacement,

and the �uid in the reservoir appears foamy. What should be done FIRST?

Choices:

1) Bleed the power steering system using the speci�ed procedure 2) Disconnect the steering angle sensor 3) Replace both front tires 4) Increase pump belt tension beyond speci�cation Correct Answer: Bleed the power steering system using the speci�ed procedure Explanation: Foamy �uid and groaning after hydraulic service usually indicate trapped air. The system should be bled using the manufacturer's procedure before condemning major components.Page 1

Question 2: A brake hydraulic line was replaced. After the repair, the pedal feels spongy and improves when pumped several times. What is the MOST likely cause?

Choices:

1) A clogged cabin air �lter 2) Excessive alternator voltage 3) Too much positive caster 4) Air trapped in the hydraulic system

Correct Answer: Air trapped in the hydraulic system

Explanation: Air is compressible, unlike brake �uid. Air introduced when the line was opened can produce a spongy pedal, so the system should be bled using the speci�ed sequence and procedure.Question 3: After an engine oil change, oil begins leaking heavily around the spin-on �lter as soon as the engine starts. What should the technician check FIRST?

Choices:

1) Whether the old �lter gasket remained stuck to the mounting �ange 2) Whether the oil pressure switch is unplugged 3) Whether the oil life monitor was reset 4) Whether the crankcase is one quart low Correct Answer: Whether the old �lter gasket remained stuck to the mounting �ange Explanation: A gasket from the old �lter can stick to the mounting �ange. Installing the new �lter over it creates a double-gasket condition that can leak rapidly under oil pressure, so the �ange should be checked �rst.Page 2

Question 4: A conventional 12-volt lead-acid battery has rested with no charge or load applied. Which open-circuit voltage most closely indicates a fully charged battery at moderate temperature?

Choices:

1) 12.6 volts 2) 10.5 volts 3) 14.8 volts 4) 11.8 volts

Correct Answer: 12.6 volts

Explanation: A fully charged conventional 12-volt lead-acid battery typically reads about 12.6 volts at rest. Around 14 volts is associated with charging-system voltage while the engine is running.Question 5: A hydraulic clutch pedal slowly sinks toward the �oor while steady pressure is held, and no external leak is visible. Which component is MOST suspect?

Choices:

1) Wheel speed sensor 2) Clutch master cylinder bypassing internally 3) Di�erential pinion bearing 4) Transfer case shift motor

Correct Answer: Clutch master cylinder bypassing internally

Explanation: A pedal that slowly sinks under steady pressure with no visible leak commonly indicates internal bypass in the clutch master cylinder. Hydraulic leakage past the seals prevents pressure from being maintained.Page 3
