Engine Performance 1 Final Questions and Answers 100% Pass The non-electronic spark advance of an engine is not increasing as engine rpm increases. Technician A says the vacuum advance unit may have a leaking diaphragm. Technician B says the centrifugal advance weights may be stuck. Who is correct? ✔✔Technician B only A loose spark plug is likely to cause: ✔✔Premature ignition coil failure A vehicle with an ignition system triggered by a magnetic pulse generator will not start. Technician A says that the air gap should be checked using a go no-go stainless feeler gauge. Technician B says that the air gap is not adjustable. Who is correct? ✔✔Both Technicians A and B All of the following are types of electronic ignition systems (EI) except: ✔✔distributor An engine's initial timing is set at 6 degrees ATDC; the specification is 3 degrees BTDC. Technician A says the timing is overly advanced and must be retarded 9 degrees. Technician B says the timing is overly retarded and must be advanced. Who is correct? ✔✔Technician B only An ohmmeter placed across the primary terminals of an ignition coil indicates 896 k ohms. Technician A says the coil windings are shorted. Technician B says the coil needs to be replaced. Who is correct? ✔✔Technician B only In the diagram of the V-6 engine, which color represents cylinder #1? ✔✔orange Spark plugs are being discussed. Technician A says to remove the plugs when the engine is at normal operating temperature. Technician B says to use a torque wrench to tighten them. Who is correct? ✔✔Technician B only The dwell section of a primary scope pattern represents: ✔✔the amount of time that the primary current is turned on Too high of a heat range spark plug will: ✔✔decrease plug life When diagnosing a no-start condition on a vehicle with no spark, Technician A says that the ignition module should be tested for a digital switching signal. Technician B says the Hall effect CMP sensor should be tested for a digital switching signal. Who is right? ✔✔Both A and B in the diagram of the V-6 engine, which color represents cylinder #4? ✔✔none of the above A 4 cylinder engine has the following firing voltages: 6 KV, 12 KV, 7 KV, and 7 KV. Technician A states that all plugs are firing within the normal range. Technician B states that there is too much variation between the highest and lowest values. Who is correct? ✔✔Both Technicians A 6 cylinder engine with a coil on plug ignition system has how many coils? ✔✔6 A 6 cylinder engine with a distributor ignition system has how many coils? ✔✔1 A 6 cylinder engine with a waste spark system has how many coils? ✔✔3 A coil is being checked, with the following results. What does the reading mean? OL ✔✔The coil secondary is open. A coil is being tested using current ramping. The waveform should ________. ✔✔Start off flat then slope upward A compression-sensing ignition system uses a ________ type ignition. ✔✔Waste-spark A distributor ignition (DI) system has a Hall-Effect type
