Question

Quizplus · Accepted Answer

When the front wheels are turned fully to the right or left, the pressure in the power steering system reaches its maximum, causing the pressure relief valve in the power steering pump to open. This prevents damage to the system by relieving excess pressure. Technician B is incorrect because the pressure is not low at this point; it is actually at its highest, which triggers the relief valve.
