ASE Practice Test #5
All of these claims about replacing and removing transmissions are accurate, EXCEPT:
Explanation:
Disconnecting the negative battery cable is the first thing you need to do. The driveshaft should always be marked for balancing purposes.
On an electronic DI system, the negative primary coil connection connects the 12-volt test light to ground. When the engine starts, this light flutters. When the coil secondary wire is connected to ground when the engine is cranking, a spark tester likewise doesn't light. Which explanation is the MOST plausible one?
Explanation:
The ignition coil trigger device is functional if the test light blinks on and off. Despite this, the lack of spark suggests a malfunctioning coil. None of the other options would result in these symptoms.
What should you do first when trying to diagnose coolant consumption?
Explanation:
The source of the leak is discovered via the cooling system pressure test. It accomplishes this by pressurizing the cooling system in the same way that it would if everything were normal. Prior to this test, there is no need to physically check for leaks.
When loaded, the transaxle abruptly shifts out of gear. Which of these is MOST likely to be the cause?
Explanation:
The transaxle may jump out of gear if the shift linkage is worn, faulty, or loose. Hard shifting is caused by old or broken synchronizers as well as an unadjusted clutch. Noise while going backwards would result from weak cover springs.
Which of these places doesn't frequently have coolant leaks?
Explanation:
Coolant might leak out of the vent hole when the water pump's shaft seal is damaged. Hoses can develop pinholes, cracks, or splits that allow coolant to flow. The plugs corrode internally, which causes leaking.
What roughly sized amount of refrigerant is released from the AC compressor high-pressure release valve?
Explanation:
The high-pressure relief valve prevents the compressor from locking up when pressures are too high. Due to the high pressures, this could possibly result in additional damage. At around 475 psi, this component releases refrigerant (3,275 kPa).
Which of the following tasks does the torque converter need to perform when the engine is removed from a car with an automatic transmission?
Explanation:
The transmission should continue to use the torque converter. If it’s left on the engine, the oil will begin to leak out. It can result in damage to the front pump and torque converter.
All of these claims about the A/C-heater control panel service are true, WITH THE EXCEPTION OF:
Explanation:
You must follow specific procedures whenever you test, examine, replace, or service the heating and A/C control panel assemblies. You should first unplug the negative battery cable. Then, you must wait a predetermined amount of time before starting to work on the panel.
Before removing the transmission or transaxle from the vehicle, all of these components APART from
Explanation:
Before removing the transmission or transaxle, a front bearing retainer cannot be removed. On the front of the transmission is where you'll find the front bearing retainer. Before the transmission is taken out of the car, all of the additional parts can be taken off.
The following causes are the least likely to result in blue exhaust emissions:
Explanation:
Oil smoke coming from the exhaust could be a sign of a broken cylinder head. Blue exhaust smoke can also be caused by worn piston rings. Blue smoke may be produced by worn valve seats that are allowing oil to leak into the cylinder.
Which of the following is determined by the automatic transmission pressure test?
Explanation:
Lower line pressure results from a filthy transmission filter. Unrestricted air cannot pass through it. A reduced line pressure would not be brought on by a faulty torque converter, shift solenoid, or ESO.
