DTC P0717 Turbine Speed Sensor Circuit No Signal: Description

WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.

This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT) with the speed sensor signal (SPD), the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure in response to various conditions, thus performing smooth gear shifting.
