DTC P0717 Input Speed Sensor Circuit No Signal

DESCRIPTION

P0717:

This sensor detects the rotation speed of the turbine. By comparing the input turbine speed signal (NT) with the output shaft speed signal, the ECM detects the shift timing of the gears and controls the engine torque and hydraulic pressure according to various conditions. As a result, smooth gear shift is achieved.

MONITOR STRATEGY:

MONITOR DESCRIPTION
The input speed sensor detects the transmission input shaft speed. The ECM determines the gear shift timing based on a comparison of the input speed sensor (input shaft speed) with the output speed sensor (output shaft speed).

When the output shaft speed is higher than the expected value and the input shaft speed is 300 rpm or less while running with the shift lever on D, the ECM will conclude that there is malfunction of the input turbine speed sensor (NT). The ECM will illuminate the MIL.
