Abstract: A sensor assembly for a sliding camshaft of a motor vehicle is provided. The sliding camshaft includes a base shaft that extends along a longitudinal axis and rotates about the longitudinal axis. The sliding camshaft further includes lobe banks rotationally fixed to the base shaft. Each lobe bank is axially movable between first and second positions relative to the base shaft. The sensor assembly includes a detection element rotationally fixed relative to the base shaft and axially movable between first and second positions relative to the base shaft. The sensor assembly further includes a sensor operably coupled to the detection element and configured to generate a signal indicative of an axial position of the detection element relative to the base shaft and at least one of an angular speed of the base shaft and an angular position of the base shaft about the longitudinal axis.
