Question

20.) technician a says that the pressure relief valve should be removed before performing a power steering pressure test
technician b says that when performing a power steering pressure test, the pressure will be highest when the wheels are in the straight ahe
who is right?
oa. a only
ob. b only
oc. both a and b
od. neither a nor b

Explanation:

• For a power - steering pressure test, the pressure relief valve should not be removed. Removing it would disrupt the normal operation and testing of the power - steering system.
• When performing a power - steering pressure test, the pressure is highest when the wheels are turned to the lock (fully turned) position, not when they are straight - ahead. When the wheels are straight - ahead, the fluid flow is relatively unrestricted compared to when the wheels are at the lock position where the resistance is maximum.

Answer:

D. Neither A nor B
