SPECIAL FEATURES OF THE ME 7.4.6 INJECTION SYSTEM
1 MOTORISED THROTTLE BODY
Given that the motorised throttle body cannot make any adjustments between the actual value measured by the
potentiometers and the mechanical position of the throttle, the ME 7.4.6 computer must be programmed to take
over this operation.
During this operation, the position of the lower mechanical stop and the limp-home position on the throttle are
programmed, and the potentiometer amplifier is balanced. The programmed values are stored in the computer
memory. The limit programming + storing of the programmed values sequence equates to initialisingthe
motorised throttle unit. The springs in the motorised throttle body are also tested.
The above initialisation process runs automatically and independently when the ignition is switched on, but only
under certain input conditions. It may run several times when the ignition is on.
