Temps Test Technical Aptitude 3 — Questions and Answers
Question 1: Which fluid should you check to ensure your steering wheel turns easily in a power steering system?
- Transmission fluid
- Power steering fluid (Correct answer)
- Brake fluid
- Windshield washer fluid
Correct answer: Power steering fluid
Power steering fluid provides hydraulic pressure that assists the driver in turning the steering wheel with less effort.
Question 2: What is the function of a vehicle's differential?
- It balances fuel delivery between cylinders
- It allows wheels on the same axle to rotate at different speeds (Correct answer)
- It controls the anti-lock braking system
- It connects the engine to the transmission
Correct answer: It allows wheels on the same axle to rotate at different speeds
The differential allows drive wheels to rotate at different speeds, which is essential when turning corners.
Question 3: If your headlights flicker while driving, the most likely cause is:
- Overinflated tires
- A failing alternator or loose battery connection (Correct answer)
- Low windshield washer fluid
- Worn brake pads
Correct answer: A failing alternator or loose battery connection
Flickering headlights typically indicate an electrical issue such as a weakening alternator or a loose/corroded battery terminal.
Question 4: What type of braking system uses hydraulic fluid pressure to activate the brakes?
- Mechanical drum brakes
- Hydraulic disc or drum brakes (Correct answer)
- Electric regenerative brakes
- Air brakes
Correct answer: Hydraulic disc or drum brakes
Most passenger vehicles use hydraulic braking, where pressing the pedal forces brake fluid through lines to activate calipers or wheel cylinders.
Question 5: What should you do if your accelerator pedal becomes stuck while driving?
- Turn off the ignition immediately while steering
- Shift to neutral, apply the brakes, and pull over safely (Correct answer)
- Pump the gas pedal repeatedly
- Open the car door to slow down
Correct answer: Shift to neutral, apply the brakes, and pull over safely
Shifting to neutral disengages the engine from the wheels so you can brake and steer safely to the roadside.
Question 6: Why is it important to rotate your vehicle's tires regularly?
- To improve fuel octane rating
- To ensure even tread wear and extend tire life (Correct answer)
- To reduce brake fluid consumption
- To balance the engine load
Correct answer: To ensure even tread wear and extend tire life
Rotating tires redistributes wear patterns because front and rear tires wear differently, extending the life of the full set.
Question 7: What does it mean when you see the battery warning light illuminate on your dashboard?
- Battery is fully charged
- The electrical charging system is not functioning properly (Correct answer)
- Time for a routine oil change
- Transmission fluid is low
Correct answer: The electrical charging system is not functioning properly
The battery warning light indicates the charging system (usually the alternator) is not supplying enough power to keep the battery charged.
