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.
