DTC P1725
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT)
and the counter gear speed sensor signal (NC), the Engine and ECT ECU detects the shift timing of the gears
and appropriately controls the engine torque and hydraulic pressure in response to various conditions, thus
performing smooth gear shifting.
DTC No.
The Engine and ECT ECU detects conditions (a), (b), (c), (d)
and (e) continuity for 5 seconds or more.
(1–trip detection logic)
(a) Gear change not being performed
P1725
(b) Gear position: 2nd, 3rd or O/D gear
(c) Solenoid valves and neutral start switch are normal
(d) T/M input shaft rpm: 300 rpm or less
(e) T/M output shaft rpm: 1,000 rpm or less
