DTC P0717 Input Speed Sensor Circuit No Signal

CIRCUIT DESCRIPTION

DTC Detection Condition:

This sensor detects the rotation speed of the O/D input shaft from the rotation of the O/D direct clutch drum.

Its mechanism is the same as that of the vehicle speed sensor.

By comparing the O/D direct clutch speed signal with vehicle speed sensor signal, the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure in response to various conditions, thus doing smooth gear shift.




Refer to the chart for the waveform between terminals NCO+ and NCO- during engine idling.
