What is the principle of the eccentric shaft sensor?

[DelBryce]

The principle of the eccentric shaft sensor is based on the magnetoresistive effect. The eccentric shaft sensor is equipped with two independent angle sensors with opposite characteristics. When the nearby magnetic field changes position, the ferromagnetic conductor changes its own resistance. Relevant information about the eccentric shaft sensor is as follows: 1. Introduction: The eccentric shaft sensor detects the position of the eccentric shaft when equipped with an electronic valve control system. The eccentric shaft adjusts the camshaft to achieve the optimal intake valve lift in each operating state (the intake valve lift can be adjusted steplessly). 2. Measurement range: The measurement range of the sensor is 180°. The sensor is supplied with 5V voltage by the engine control unit DME. Data from the eccentric shaft sensor to the DME is transmitted at a medium clock frequency of 250kHz.
