Engine Speed Limitation

OPERATION
The Electronic Throttle Control (EML) control unit limits the engine speed by closing the throttle valve before reaching the limit speed. The limit speed is 6000 rpm. To avoid control problems between the EML and Digital Motor Electronic (DME) systems when limiting the engine speed, DME control of engine speed limitation is set to 6200 rpm. The EML control unit detects the engine speed by way of the engine speed signal Engine Speed Signal (TD) from the DME control unit. Engine speed limitation by the EML control unit is only active when a drive range is engaged.
