Idle Speed: Notes

The crankshaft sensor delivers a signal regarding the position of the crankshaft to the Digital Engine Electronics (DME). The Digital Engine Electronics (DME) use this signal to calculate the engine speed. With additional information from other control units (for example, power requirement of the auxiliary components), the Digital Engine Electronics (DME) regulate a stable idle speed.
