DTC P0717 TURBINE SPEED SENSOR CIRCUIT NO
SIGNAL
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT)
with the counter gear speed sensor signal (NC), the ECM detects the shift timing of the gears and appropri-
ately controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear
shifting is performed.

ECM detects conditions (a), (b), (c) and (d) continuity for 5 sec.
or more: (1 trip detection logic)
(a) Vehicle speed: 50 km/h (20 mph) or more
(b) 2nd, 3rd or O/D gear
(c) Solenoid valves and park/neutral position switch are normal
