DTC P0717, P07BF, P07C0; Input/Turbine Speed Sensor "A" Circuit No Signal [08/2017 - ]: Description

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

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

The transmission revolution sensor (NT) detects the continuously variable transaxle input shaft speed and sends a signal to the ECM.
