I never paid attention to the thing before apparently, but busy with my wheels, this sensor caught my attention, and made me wonder,
what is it for...?
Is connected to the lower front A-arm, and thus senses the movement of the suspension (wheel travel), but why?
The sensor provides feedback to several subsystem. From light height to ABS/DSC to AWD control on AWD cars. Should the sensor indicate a very loc car, it will disable AWD. It is used by DSC and ABS to determine the optimal pressure to apply to each axle (this is just one of the sensors used along with gyro, accelerometers, angular wheel speed, steering angle, speed etc).

In other words, gone are the days of simple cars (with some exceptions)...
