ASE Practice Test #2 2

Question 1

A vehicle's power steering is hard to turn at low speeds but normal at highway speeds. What component is MOST likely responsible?

Accepted Answer

A faulty or worn power steering pump not developing adequate pressure at low RPM, or a failing flow control valve

Answer

Failed rack-and-pinion steering gear

Answer

A bent tie rod end

Answer

Overinflated tires

Question 2

During a transmission fluid level check on an automatic transmission with a dipstick, the technician finds the fluid level is correct but the fluid is dark brown and has a burnt smell. What is recommended?

Accepted Answer

Change the transmission fluid and filter — dark, burnt fluid indicates thermal degradation and potential internal clutch pack damage that requires immediate service and further diagnosis

Answer

Add a bottle of transmission flush additive and drive normally

Answer

The fluid color is normal for a high-mileage vehicle — no action needed

Answer

Add fresh fluid on top of the degraded fluid to dilute it

Question 3

What is the purpose of the mass airflow (MAF) sensor in a fuel-injected engine?

Accepted Answer

To directly measure the mass of air entering the engine, providing the primary data for the ECM to calculate the correct fuel injection pulse width

Answer

To measure exhaust gas oxygen content for fuel trim feedback

Answer

To control idle speed by varying air bypass around the throttle

Answer

To measure intake manifold temperature only

Question 4

A front-wheel drive vehicle vibrates during acceleration but not at a steady cruise speed. What is the MOST likely cause?

Accepted Answer

A worn or damaged constant velocity (CV) joint on a front axle shaft — worn CV joints typically vibrate under torque load during acceleration but can be smooth at constant load

Answer

Worn shock absorbers

Answer

Unbalanced tires

Answer

Faulty transmission mount

Question 5

What does the term "cold crank amperage" (CCA) rating indicate on a battery?

Accepted Answer

The amperage the battery can deliver for 30 seconds at 0°F (-18°C) while maintaining at least 7.2V — higher CCA means better cold-weather starting ability

Answer

The number of charge cycles the battery can perform

Answer

The charging current the battery accepts at room temperature

Answer

The maximum temperature the battery can operate at

Question 6

When diagnosing a "click-no-crank" condition, a technician hears one solid click when the key is turned to start. What does this indicate?

Accepted Answer

The starter solenoid is engaging (the single click) but the starter motor is not turning — likely a failed starter motor, seized engine, or high resistance in the starter circuit

Answer

The battery is completely dead

Answer

The ignition switch contacts are burned

Answer

The park-neutral safety switch is open
