Why
is the throttle position sensor an important sensor in electronically
controlled suspension?
So the system can compensate for changes in
vehicle load
So the system can compensate for changes in yaw
So the system can compensate for changes in body
roll
So the system can compensate for driver
acceleration and deceleration
The
most popular type of sensor used as ABS wheel speed sensors is the inductance
type speed sensor. What type of output does it deliver?
Ohms
DC Volts
Amps
AC volts
After
rectifying an engine fault you need to road test the customer's vehicle. Before
you start the test it is essential that you:
complete the job card with all details
concerning the vehicle repair
ensure your work bay is tidy and all tools have
been put away
check that you hold the correct driver's license
for the vehicle
check the vehicle's tyre pressures, oil level
and windscreen washer fluid
What
is the function of the actuator distance sensor?
To prepare the gearbox for the next gear
To judge clutch disengagement position
To allow the vehicle to freewheel in neutral
To ensure reverse gear can’t be selected whilst
moving
It
is important to accurately record on the job card the time you have spent
repairing a vehicle with a complex diagnostic fault because:
it will reduce the company's profit
it will ensure you get paid correctly
it will affect your labour efficiency
it will affect the customer's charges
You
are testing the power to the electric servo unit on an electric power steering
system. You rotate the wheel first in one direction then another. What readings
would you expect to get?
Changing voltage levels, constant current
Varying current levels, on-off voltages
dependant on position, fixed polarity
Varying current levels, fixed voltages, fixed
polarity
Varying current levels, on-off voltages
dependant on position, reversible polarity
What
is one of the main advantages of electrically assisted power steering?
Better fuel economy due to less engine load
Maintenance free due to no moving parts
No requirement for track rod ends to be adjusted
Less effort required to turn the steering wheel
What
is the term used for creating a current in a conductor?
Ohms law
Electromotive force
Electromagnetic induction
Flemings right hand rule
In
the rack and pinion type electric power steering system, what part of the
system does the motor act directly on?
Input shaft
Rack
Output pinion shaft
Track rod
Why
does electronic suspension use a speed sensor?
To make sure the system doesn't change the
suspension ride mode whilst moving
The system stiffens the suspension as speed
increases to improve vehicle control
The system stiffens the suspension as the speed
decreases to improve braking
The system softens the suspension as the speed
increases to improve comfort
Which
of the following sensors is used in electric steering systems?
Hydraulic pressure sensor
Wheel speed sensor
Gear position sensor
Optical torque sensor
You
are required to check an ABS wheel sensor. What type of tester would you use to
get a clear picture of the output?
DC voltmeter
Ammeter
Oscilliscope
AC voltmeter
In the Bosch/LuK electronic clutch
actuator, what type of gearing is used?
Epicyclic gearing
Rack and pinion
Recirculating ball
Worm and Gear
Which
of the following is NOT a DIRECT cost of carrying out a vehicle repair?
The consumable materials used during the repair
The parts fitted to the vehicle during the
repair
The technician's time spent carrying out the
repair
The receptionists time dealing with the customer
You
have been given the task of testing a ZF servotronic steering system that is not
varying hydraulic pressure with speed. You suspect the speed sensor is the
faulty component. What piece of test equipment would be the most efficient to
use?
Multimeter
Ammeter
Oscilliscope
Ohmmeter
What type of signal does a multiplex system use
analogue
digital
graphical
binary codes
How would you test a wheel speed sensor?
Voltmeter
Ammeter
Oscilloscope
Ohmmeter
What controls the damper height control?
Orifice size
Springs
Damper length
Where is the power steering motor mounted?
The column
Steering rack
Steering arm
Universal joint
What is a potentiometer?
Variable fuse
Variable relay
Variable resistor
If a vehicle starts driving and the ABS light comes on, what could be the common fault?
A faulty wheel speed sensor
Alternator
Flat tire
Seized caliper
What does EHT stand for?
Electro Hydraulic transmitter
Electro Hydraulic Transporter
Electro Hydraulic Transducer
Electro Hydraulic Transgender
When the steering is straight, what will the sensor read?
5 Volts
