ASE Preventive Maintenance & Inspection (PMI) Practice Test

Preventive maintenance and inspection work centers on identifying visible safety concerns, checking routine service items, and recording conditions that may need attention. H8 practice questions sample walk-around and under-vehicle checks, fluid and tire observations, basic component inspection, and decisions about when to document a finding or recommend further service.

About the ASE Preventive Maintenance & Inspection (PMI) Exam

A preventive inspection requires a consistent sequence: make the vehicle safe to inspect, check accessible components, compare observable conditions with markings or specifications, and communicate findings clearly. Relevant skills include using a tread-depth gauge, inspecting fluid levels and leaks, recognizing damaged mounts or swollen battery cases, and checking basic functions such as the horn and windshield washers. Technicians also need to distinguish an observation from a confirmed diagnosis—for example, documenting fresh fluid at a hose connection without assuming its source—and identify conditions that warrant further evaluation. These tasks support maintenance planning, vehicle safety, and accurate service records. The practice bank samples decisions about inspection responses, including what to check next, what to document, and when a condition should be addressed rather than overlooked.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

During an inspection, a technician notices that the windshield washer spray does not reach the windshield when the washer control is used. What is an appropriate response?

  1. ARecord the malfunction and recommend checking the washer fluid supply, pump, and spray outlets
  2. BReplace the windshield wiper motor
  3. CAim the washer outlets toward the roof to reduce fluid use
  4. DConclude that the washer system is functioning because the wipers move
Show answerCorrect answer: A

Washer performance depends on adequate fluid and a functioning pump, hoses, and outlets. The malfunction should be recorded and those parts checked as appropriate; wiper movement alone does not confirm washer operation.

Question 2

During an under-vehicle inspection, a technician finds fresh fluid at a steering hose connection. What should be documented or checked next?

  1. AIgnore it if the steering feels normal during a brief test
  2. BIdentify the fluid source and inspect the connection and nearby components for leakage
  3. CWipe it away and record no concern without rechecking
  4. DTighten every nearby fastener to maximum force
Show answerCorrect answer: B

Fresh fluid should be traced to its source because appearance alone may not identify the fluid or the leak point. Inspect the connection and surrounding components, and document the finding for appropriate repair evaluation.

Question 3

A vehicle's horn does not sound when the driver presses the horn pad. What is an appropriate preventive inspection action?

  1. ARecord the horn as inoperative and recommend diagnosis or repair
  2. BReplace the steering wheel immediately
  3. CIncrease engine idle speed
  4. DLubricate the tires
Show answerCorrect answer: A

An inoperative horn is a safety-related defect to document and refer for diagnosis or repair. The symptom alone does not identify a specific failed component.

Question 4

During a visual inspection, a technician finds a cracked engine mount with visible separation of its bonded material. What is the most appropriate response?

  1. ADocument the damage and recommend evaluation of the mount and related powertrain supports
  2. BApply adhesive to the crack and consider the mount repaired
  3. CTighten the wheel lug nuts to reduce engine movement
  4. DIgnore the condition unless the engine stalls
Show answerCorrect answer: A

A separated or cracked mount may no longer properly support or restrain the powertrain. The finding should be documented and evaluated; an improvised adhesive repair does not restore the designed support.

Question 5

A battery case is visibly swollen. Which inspection response is most appropriate?

  1. ATreat it as a potentially damaged battery and follow safe handling and replacement procedures
  2. BPry off the battery caps to release pressure
  3. CCharge it at the highest available rate before inspecting further
  4. DTap the case until it returns to its original shape
Show answerCorrect answer: A

A swollen battery case may indicate internal damage or abnormal conditions. Avoid puncturing, heating, or aggressively charging it; use appropriate protective equipment and follow safe battery handling procedures.

Question 6

When checking brake fluid level in a transparent reservoir, what should a technician do if the level is below the minimum mark?

  1. ATop it off and return the vehicle without further checks
  2. BAdd engine oil until the fluid reaches the maximum mark
  3. CInspect for leaks and assess brake lining wear before determining the cause
  4. DOpen the bleeder screws to raise the reservoir level
Show answerCorrect answer: C

A low brake-fluid level may result from a leak or from fluid displacement as brake linings wear. Identify the cause and inspect the hydraulic system rather than simply topping off and dismissing the condition.

Question 7

During a routine vehicle inspection, what is the safest first step before working near moving engine components?

  1. ARemove jewelry and secure loose clothing, then keep hands clear of belts and fans
  2. BPlace a hand on the fan shroud to check for vibration
  3. CStart the engine with tools resting on the radiator support
  4. DDisconnect the battery only after testing the starter
Show answerCorrect answer: A

Loose clothing and jewelry can become caught in rotating parts. Keep hands, tools, and clothing clear of belts and fans, which may start unexpectedly on some vehicles.

How to use this practice test

Access the free H8 practice questions and work through a session of up to 20 randomly selected items from the 50-question bank. After the session, review your results to identify inspection decisions that need more attention, such as fluid checks, tire measurement, safe work practices, or documenting visible defects.

Preparation tips

  • Practice measuring tire tread with a tread-depth gauge, and distinguish a direct measurement from a visual estimate.
  • Review safe inspection setup around moving engine parts, including when the engine should be off before reaching into the compartment.
  • For fluid leaks, damaged mounts, swollen batteries, and low reservoir levels, separate what you observed from the next check or service action.
  • Rehearse routine function checks for the horn and windshield washers, and note how to describe a failure clearly in an inspection record.
  • Compare visible service items such as a debris-clogged cabin air filter or a missing cover fastener, and decide whether replacement, correction, or documentation is appropriate.
