P1725

DTC P1725 NT Revolution Sensor Circuit Malfunction

DTC Detection Condition:

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 appropriately controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shifting is performed.

HINT: Check the input turbine speed sensor (NT) when DTC P1725 (NT Revolution Sensor Circuit Malfunction) is output.
