Sample ASE4 - ASE Automobile Engine Performance Practice Questions

Try these questions from our free ASE4 - ASE Automobile Engine Performance practice tests. The correct answer and an explanation follow each question.

An engine has a wet compression test reading significantly higher than the dry test. This indicates:
- A. A blown head gasket
- B. Worn or damaged piston rings
- C. Leaking intake valves
- D. A cracked cylinder head

Answer: B. Worn or damaged piston rings

Adding oil temporarily seals worn rings, causing a wet reading much higher than the dry reading.

A technician finds fuel pressure holds for 30 seconds after the engine is shut off but then bleeds down slowly over several minutes. This MOST likely indicates:

A. A faulty check valve in the fuel pump
B. Normal pressure bleed-down for a returnless system
C. A leaking fuel injector
D. A failing fuel pressure regulator

Answer: C. A leaking fuel injector

Slow bleed-down of residual fuel pressure after shutdown typically indicates a leaking fuel injector allowing fuel to drip into the intake.

What is the standard OBD II communication protocol required in most vehicles manufactured since 2008?

A. ISO 9141-2
B. J1850 VPW
C. CAN (ISO 15765-4)
D. J1850 PWM

Answer: C. CAN (ISO 15765-4)

CAN (Controller Area Network, ISO 15765-4) became the mandatory OBD II protocol for all US vehicles from 2008 onward, replacing older protocols like ISO 9141-2 and J1850.

What does a P0300 code (Random/Multiple Cylinder Misfire) indicate?

A. Only cylinder #1 is misfiring
B. Misfires are detected across multiple cylinders or cannot be isolated to one
C. The ignition system has failed completely
D. The fuel injectors are all misfiring in sequence

Answer: B. Misfires are detected across multiple cylinders or cannot be isolated to one

P0300 indicates misfires occurring across multiple cylinders or randomly, pointing to a common system fault rather than a single cylinder issue.
