EML System Overview

Throttle valve control is managed electronically, using an electric motor(s), without the use of mechanical linkages or cables (except E46 - MDK).

The EML system uses a microprocessor to convert the input signal for the position of the accelerator pedal into output commands for control of the throttle valve. The position of the pedal is merely a request to the control module for throttle opening. The EML module processes this input request along with other pertinent operating parameters. The throttle valve is then moved to its proper position according to specific control unit programming.

The total scope of output control functions for the EML includes:
