Tech A
Tech B
Both A and B
Neither A nor B

The power steering system is designed so that the vehicle can still be controlled even if the engine or the power steering system were to fail—though greater effort would be required.
True
False
Reduction ratio is measured in:
Select one:
millimeters
inches.
feet.
degrees.
Steering ratio is not the same on all vehicles and is designed by engineers to provide the best steering response for the vehicle.
True
False
The steering box converts the rotary motion of the steering wheel into:
reciprocating motion.
angular motion.
lateral motion
tangential motion.
Tech A says that when the vehicle is being driven straight ahead, a belt-driven power steering pump will pump fluid continuously, placing a minimal load on the engine. Tech B says that a belt-driven power steering pump is activated by an electromagnetic clutch, so it only pumps fluid when the wheels are being steered. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
When the driver moves the steering wheel, the hydraulic pressure is sent to the ________.
Steering rack
Pitman arm
Steering linkage
Either A or B

Tech A
Tech B
Both Techs A and B
Neither Tech A nor B
Tech A says that on a hydraulic power steering system the power steering switch turns off the power steering pump if the pressure gets too high. Tech B says that on the same system, the power steering switch is used to turn on the pump if the pressure gets too low. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
There are three types of power steering, including all of the following EXCEPT:
hydraulically assisted power steering.
dual-hybrid power steering.
