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

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

By comparing the O/D direct clutch speed signal to 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.




DETECTING CONDITIONS




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