Which service consultant is correct about the components related to engine speed data transmission?

The assertion made by Service Consultant B is likely correct regarding the components related to engine speed data transmission. Engine speed data transmission is a vital part of modern automotive systems, especially with the integration of electronic control units (ECUs) and other onboard diagnostics.

Typically, engine speed information is derived from various sensors, such as the crankshaft position sensor or camshaft position sensor, which transmit data to the engine control module (ECM). This information is crucial for the engine's performance, efficiency, and emissions control, as it helps manage fuel injection, ignition timing, and other aspects of engine management.

Consultant B’s understanding aligns with the technical protocols and systems in place within modern vehicles, which prioritize accuracy and reliability in data transmission to enhance vehicle performance and diagnostics. This insight illustrates the significance of knowledge in electronic systems, particularly as vehicles continue to include more complex networking and data management strategies.
