Pedal position data is sent by the engine management system over the P-bus.

The ESP control module uses the information on pedal position to determine the degree of wheel spin to allow during ESP/TCS modulation. The system considers the pedal position to be the degree of aggressiveness the driver requests and allows a greater degree of wheel spin the more the pedal is depressed (pedal position increases as a percentage).
