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 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.
DTC No.DTC Detecting ConditionTrouble Area
P1705

nuity for 4 secs. or more.
(2-trip detection logic)
(a) Gear change not being performed
(b) Gear position: 1st, 2nd 3rd or O/D
(c) T/M input shaft rpm: 300 rpm or less
(d) T/M output shaft rpm: 1,000 rpm or more
(e) Park/neutral position switch: OFF
