Technician A says throttle-by-wire systems (ETC)eliminate the need for a cruise control actuator. Technician B says ETC also allows the PCM to be more effective when limiting engine and vehicle speeds. Who is correct?

Both statements are correct. Throttle-by-wire systems eliminate the need for a mechanical connection between the accelerator pedal and the throttle, allowing for the integration of cruise control functionality without a separate actuator. They also enable the Powertrain Control Module (PCM) to more effectively manage engine and vehicle speeds by electronically controlling the throttle.
