DTC P1705 NC2 Revolution Sensor Circuit Malfunction
(Direct Clutch Speed Sensor)
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the direct clutch drum.
By comparing the direct clutch speed signal and 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.

DTC P1765Linear Solenoid for Accumulator Pressure Control
Circuit Malfunction (Shift Solenoid Valve SLN)
CIRCUIT DESCRIPTION
The shift solenoid valve SLN controls the hydraulic pressure
acting on the accumulator control valve when gears are shifted
and performs smooth gear shifting.
The ECM determines optimum operating pressure according to
the signals from the throttle position sensor, vehicle speed sen-
sor and direct clutch speed sensor and controls the volume of
current flow to the solenoid valve.
The amount of current to the solenoid is controlled by the (*)
duty ratio of ECM output signals, causing a momentary change
to the hydraulic pressure acting on the clutches during gear
shifting.
When the duty ratio is high, the hydraulic pressure acting on the
clutches is low.
DTC No.DTC Detecting ConditionTrouble Area

After the engine is warmed up, the current flow to the shift
solenoid valve SLN for 1 sec or more under condition (a) or
