DTC P0715: Input / Turbine Speed Sensor Circuit Malfunction; DTC P0717: Input Speed Sensor Circuit No Signal: Description
WARNING: This page is about a different car, the 2013 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
This sensor detects the rotation speed of the turbine which shows the input revolution (speed) of the transaxle. By comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (NC), the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to various conditions, thus, providing smooth gear shifts.
