Crankshaft Pulse Pick-up, X 18 XE1 and X 20 XEV The crankshaft pulse pick-up is responsible for detecting the crankshaft speed. The crankshaft pulse pick-up functions on the inductive measuring principle. The voltage induced is therefore directly proportional to the speed of the increment disc. In the X 18 XE1, the crankshaft pulse pick-up is attached to a lug on the oil pump and uses the torsional vibration damper (increment disc) to detect the rotational speed. In the X 20 XEV, the crankshaft pulse pick-up is attached to the cylinder block and uses a pulse pick-up (increment disc) bolted onto the crankshaft to detect the rotational speed. The crankshaft pulse pick-up transmits a signal to the engine control unit, which uses it to calculate the crankshaft speed.
