Using a diagnostic strategy for engine repair, which of the following is generally the last step in that
process
A. Checking vehicle history
B. Verifying the repair
C. Doing service check
D. Verifying the concern - correct answer ✔✔B
All of the following tools are used to assess the mechanical condition of an engine, EXCEPT
A. Compression tester
B. DMM (Digital Multimeter)
C. Vacuum gauge
D. Scam tool - correct answer ✔✔B
A DMM or Digital multimeter is used to measure current, voltage, resistance, and electrical and is not
used to assess an engines mechanical condition.
The compression tester measures the amount of compression pressure a cylinder can generate
The vacuum gauge measures the amount of vacuum an engine can generate.
An engine cranks but will not start. Which of the following should be checked first?
A. Check for spark
B. Check for fuel
C. Check engine compression
D. Check engine timing - correct answer ✔✔A
,Without ignition, an engine will crank but will not start. The other three choices are all possible source of
a no-start when the engine cranks but would not be the first thing a technician should check.
An engine cranks but will not start and the scan tool shows DTC (Diagnostic Trouble Code) P1320
(Ignition Signal) stored on a vehicle with a disrtibutor-type single ignition coil. What is the next step after
verifying the concern?
A. Perform an input signal circuit check
B. Check for power to the coil
C. Check the power transistor's ground circuit
D. Perform a power transistor output circuit check - correct answer ✔✔B
The first step of most diagnostic procedures is to attempt to start the engine. Since the stem states that
the engine will not start due to a lack of spark, the next step tells you to check for B+ power to the
ignition coil.
An orange colored liquid is found at the front of the engine. What is leaking?
A. Engine oil
B. Coolant
C. Automatic Transmission Fluid
D. Washer Fluid - correct answer ✔✔B
Coolant can be orange, pink or green. Engine oil is yellow or brown. ATF is red and washer fluid is blue
Which of the following creates a flapping sound near the front of the engine?
A. Timing belt tension too tight
B. Drive belt too tight
C. Drive belt too loose
D. Timing belt tension too loose - correct answer ✔✔D
, An engine noise sounds like a knock at the side of the engine that is louder when the engine is cold and
goes away or is reduced when the engine reaches operating temperature. Which of the following is the
most likely cause?
A. Cam bearing
B. Main bearing
C. Wrist pin
D. Piston slap - correct answer ✔✔D
Which of the following should be the first step in diagnosing an under hood engine noise?
A. Discussing noise with the vehicle owner
B. Retrieve (DTC) Diagnostic trouble codes
C. Check for symptoms in the on-line service manual
D. Road test the vehicle - correct answer ✔✔A
Discussing noise with the owner and then road test and then checking for symptoms in the online
A cog type or teeth of the rubber timing belt that is tight will make what type of noise?
A. Thumping sound
B. Whining sound
C. Slapping sound
D. Will not make sound - correct answer ✔✔B
All of the following are true regarding oil dilution (묽게함)
A. Result of unburned fuel getting into the oil
B. Caused by an overly rich air-fuel mixture
C. Higher at normal operating temperature
