DTC P0715: Input / Turbine Speed Sensor Circuit Malfunction; DTC P0717: Input Speed Sensor Circuit No Signal [12/2013 - 08/2014]: Description
WARNING: This page is about a different car, the 2016 Toyota Highlander, 2015 Toyota Highlander, and 2014 Toyota Highlander. 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 indicates the input shaft revolution (speed) of the transaxle. By comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (NC), the TCM 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.
