The Input Sensor of RXC Auto transmission is composed of S1(Sensor1) and S2(Sensor2). S1 inputs signal to TCM only at 4th gear and S2 does at 1st, 2nd, 3rd, 4th and 5th gear.
Therefore, sensing pulse frequency outputted from sensor 2, TCM calculates Inputshaft speed and compute Turbine rotation.. This value is mainly used to control the optimum fluid pressure during shifting.
The TCM sets this code if an output pulse-signal is not detected, from the INPUT SPEED SENSOR 1 or 2, when the vehicle is running faster than 40km/h. The Fail-Safe function will be set by the TCM if this code is detected.
