Middle speed sensor is one body and installed in transmission. It's used hall sensor of an electric current type, and current is changed by magnetic variation. Each sensors are composite 2 pins and PCM/TCM supplied power to sensor and controled by PCM/TCM.
This code is set when vehicle speed is above 20km/h but middle speed signal is not detected by middle speed sensor.

Middle speed sensor
Under 1000RPM, Output waveform is 60 or 120µs(ON time) by shaft of rotation
Over 1000RPM, Output waveform is 30µs(ON time)
