3. technician a says passive permanent
magnet abs wheel speed sensors produce an
a/c voltage signal. technician b says input
from wheel speed sensors are used for anti-
lock brake, electronic traction control, and
electronic stability control systems. who is
correct?

Both technician A and B

Explanation:

Passive permanent  magnet ABS wheel speed sensors produce an  A/C voltage signal. Wheel speed sensors are a necessary ABS component and sensor input. It is used to inform the ABS control module of rotational wheel speed. A passive sensor creates an AC signal that changes frequency as the wheel changes speed. Moreover, input  from wheel speed sensors are used for anti- lock brake, electronic traction control, and  electronic stability control systems. Therefore, both technicians are correct.

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.
