The input(turbine) speed sensor outputs waveform signals according to the revolutions of the input shaft ,installed in front of End clutch retainer,of the transmission. The TCM determines the input shaft speed by calculating the frequency of the pulses. This value is mainly used to control the optimum fluid pressure during shifting.
The TCM sets this code if an expected high rpm detected, The Fail-Safe function will be set by the TCM if this code is detected.
