I searched for this on this forum and didn't find a whole lot of info on it, but I'm wondering what exactly this drive-by-wire system is? When Googled their definition of drive-by-wire is that ALL systems, steering, braking, etc. are wire-controlled and have no hydraulics or mechanisms.

However, I'm pretty sure too that I read the Civic's only have drive-by-wire as it pertains to the throttle. Can anyone give me a more detailed explaination of how this system works?

 

You are correct. DBW on the civic only pertains to the throttle system. The steering is electronically assisted, as opposed to mechanically driven off belts (at least on the Si).

 

i dont know if someone explained this to you yet but the drive by wire means that instead of the car having a mechanical cable from the gas pedal to the throttle plate there is an electric sensor on the gas pedal and it tells a computer to activate an electric motor ont the throttle body that opens and closes the throttle plate.
