Variable reluctance sensor - Wikipedia, the free encyclopedia
A variable reluctance sensor (VRS) is used to measure position and speed of moving metal components. This sensor consists of a permanent magnet, a ferromagnetic pole piece, a pickup coil, and a rota...

The variable reluctance sensor is strain-based, wherein a magnetic circuit is formed, and the parameter input causes mechanical deflection of the spring member as a function of pressure, force, or acceleration.

Unlike sequentially injected engines that require a camshaft signal or sensor, there is no need for a camshaft signal on EDIS systems in multi-port injected engines. The VRS provides engine speed data and the signature pulse needed to properly sequence multiport injectors and the ignition coils.
