DTC P0715: Input/Turbine Speed Sensor "A" Circuit; DTC P0717: Input/Turbine Speed Sensor "A" Circuit No Signal [06/2015 - ]: Description

The ECM receives a signal from the transmission revolution sensor (NT) installed to the continuously variable transaxle to control the lock-up engagement pressure and forward and reverse clutch pressure.

The transmission revolution sensor (NT) detects the input turbine speed and sends a signal to the ECM.
