DTC P0715 Input/Turbine Speed Sensor Circuit Malfunction; DTC P0717 Input Speed Sensor Circuit No Signal: Description

WARNING: This page is about a different variant/trim than selected.

The speed sensor (NT) detects the input axis rotation speed and inputs it into the TCM as a signal. Based on the transmission speed sensor (NT) signal and the transmission speed sensor (NC3 and SP2) signal, the TCM controls engine torque and shift timing. Also, based on the input axis rotation speed and the engine speed signal, lock-up control is performed.
