Electronic power steering (EPS) operation is being discussed. Technician A says the steering sensor informs the EPS control module regarding the direction of steering wheel rotation. Technician B says the interface in the steering sensor amplifies the DC voltage signal from the steering sensor. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because the steering sensor does indeed inform the EPS control module about the direction in which the steering wheel is being turned, which is crucial for the system to provide the appropriate amount of power assistance. Technician B is incorrect because it is not the function of the interface in the steering sensor to amplify the DC voltage signal; the signal conditioning and amplification, if needed, are typically handled by the EPS control module or a dedicated signal processing unit, not the steering sensor itself.
