P0717 Input/Turbine Speed Sensor \'A\' Circuit No Signal

General Information

Component Location





General Description

The input (turbine) speed sensor outputs pulse-signals according to the revolutions of the input shaft of the transmission. The PCM/TCM determines the input shaft speed by counting the frequency of the pulses. This value is mainly used to control the optimum fluid pressure during shifting.

DTC Description

The PCM/TCM sets this code if an output pulse-signal is not detected, from the input speed sensor, when the vehicle is running faster than 30 km/h. The Fail-Safe function will be set by the PCM/TCM if this code is detected.

DTC Detecting Condition
