Question

Quizplus · Accepted Answer

Maximum power assist typically occurs at lower engine speeds to help with steering at low speeds or while the vehicle is stationary, not at 150 rpm (fast idle) which is not a typical engine speed for such conditions. The statement about maximum power assist occurring at 150 rpm while the vehicle is at rest is incorrect because 150 rpm is not a standard measure for engine speed in this context, and power assist is generally designed to be most helpful at low vehicle speeds or when stationary, regardless of engine rpm.
