DTC P1705 NC2 Revolution Sensor Circuit Malfunction
(Direct Clutch Speed Sensor)
CIRCUIT DESCRIPTION
NC2 Revolution Sensor This sensor detects the rotation speed of the direct clutch drum.
By comparing the direct clutch speed signal with the vehicle
speed sensor signal, the ECM detects the shift timing of the
gears and appropriately controls the engine torque and hydrau-
lic pressure in response to various conditions, thus performing
smooth gear shifting.
