Example #1
1.   A vacuum gauge is connected to the intake
manifold of an engine and the needle fluctuates
between (15 and 20 in Hg) at idle. This reading
indicates:

    A.  A normal condition.

    B. Late ignition or valve timing.

    C. A stuck valve or engine miss.

    D. A clogged exhaust.
Use the process of elimination to answer this question. Since the
needle is fluctuating it is highly likely it is associated with one
cylinder.

A. "It's not normal for the vacuum to fluctuate in an engine."

B. "Late ignition or valve timing effects all cylinders."

D. "A clogged exhaust would effect all of the cylinders."

C   Is the correct answer. A misfire or a burned or sticking valve
would cause this condition.
Use the Process of Elimination
Example #2
Look out for words like least and most and keep
them in mind before you begin your process of
elimination.
2.   The least likely to cause low oil pressure in an
engine is:

    A. Worn lifter bores

    B. Main bearings

    C. Camshaft bearings.

    D. Worn valve guides.
Watch for Least and Most
Except Type Question
B is the correct answer.
ASE will use the except question and you just
have to be careful and read the question and
understand what it is asking of you.
They will use the Neither Answer
The test is well balanced and though it may seem
unnatural, they will ask a question where neither of
the technicians are correct. They do and probably will!
Example #3
Example #4
1.   All of these are true about the metering
valve except:

    A. It is used on a vehicle with
    front discs and rear drums.

    B. It is a height sensing device.

    C. It gives the rear brakes a chance to
    over come the springs and engage
    with the front brakes.

    D. It is often part of the combination
    valve.

9.   Technician A says that magnetic particle detection

bow at the ends when overheated. Who is Correct?

    A. Technician A

    B. Technician B

    C. Both Technician A and B
