#. 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." Remember a steady 17 - 21 Hg. B "Late ignition or valve timing effects all cylinders." C Is the correct answer. A misfire or a burned or sticking valve would cause this condition. D "A clogged exhaust would effect all of the cylinders." |
Look for the words least and most. |
|
#. 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 |
Look out for words like least and most and keep them in mind before you begin your process of elimination. Be careful when a question contains the word could. Remember the answer does not have to be the most common or most likely choice. It does have to be a possible choice. |
Look out for the word except. |
|
#. 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 Delays front brake engagement in order to overcome rear brake spring tension. D It is often part of the combination valve. |
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. It's really all about comprehension and taking the right amount of time to read and understand the question their asking. With this type of question their only trying to point out that different parts can and will cause the same noise or symptom. Look for the one that is false or least-likely. Sometimes it has little or nothing to do with the system in question. |
It's all in the wording. |

# A cylinder power balance test is being performed on a vehicle with sequential fuel infection. Two adjacent cylinders are under performing. Technician A says this could be due to a restriction in the fuel injectors. Technician B says this could be due to leaking secondary insulation. Who is correct? A Technician A B Technician B C Both Technician A and B D Neither Technician A or B |
Remember when a question uses the word could, it does not have to be the most likely answer. It does have to be a possible answer though. Don't get confused. It could be leaking secondary insulation caused by poor wire insulation or wire routing. It could also be caused by clogged fuel injectors. It could also be caused by the valve train, worn piston rings, or a misfire. Adjacent cylinders makes a technician think faulty head gasket, but the choice is unavailable. Make sure to take enough time to understand the question and the possible choices. Just remember the test is timed so be careful not to stay on one question for too long. |
Two technicians having a discussion. |

| #. Technician A says that magnetic particle detection is an acceptable way to detect cracks in aluminum castings. Technician B says aluminum heads tend to bow at the ends when overheated. Who is Correct?
A Technician A B Technician B C Both Technician A and B D Neither Technician A or B |
ASE has used this style of question for years, since the beginning. The test is well balanced and though it may seem unnatural, they will ask a question where both or neither of the technicians are correct. This format is used on all eight A1-A8 ASE tests. The answer may be one of the technicians, both, or neither. |
