Drive-by-Wire Throttle System (All)

What’s the Benefit?

This system enhances smooth acceleration appropriate for conditions, for greater driveability.

The Feature:

Instead of a mechanical linkage from the accelerator pedal to the fuel-injection throttle plate, all Honda models use Drive-by-Wire technology.

  • The system uses an electronic position sensor connected to the accelerator pedal that sends an electronic signal to the vehicle’s powertrain control module (PCM).
  • The PCM combines the accelerator-position signal with data such as engine rpm, coolant temperature and road speed, and then optimizes the movement of the throttle plate to the desired position.
