Input/output 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 output speed signal is not detected by Output speed sensor.
