The Intermediate Shaft Speed Sensor notices the rotational speed of the input turbine. Then, it transmits this information to the required module. The input turbine speed signal (NT) is compared by the ECM with the speed from the Gear Speed Sensor (NC), thus detecting gear shift timing. Besides, it controls the hydraulic pressure engine torque regardless of different conditions. As a result, the executed gear changes are smoother.
The DTC P0793 OBDII is stored by the ECM/TCM when a signal is not detected by the Intermediate Shaft Speed Sensor A or its circuit.
