Idling control
Idling control |
The automatic idling control function is adaptive, i.e. it adapts continuously to the changes taking place throughout the life of the engine. Such changes might be wear in the engine, dirt or leakage in the intake manifold or throttle body, etc.
The control module is programmed to maintain idling speed if the speed of the car 0 km/h at the same time as the throttle position sensor indicates that the butterfly is in the idling position.
To maintain a constant engine speed, air mass compensation takes place on engagement of the A/C or secondary air injection pump and when Drive is selected on cars with automatic transmission.
With a hot engine, idling speed for the MOTRONIC 2.8.1 system is 800 rpm.
