DTC P0717 Turbine Speed Sensor Circuit No SignalDESCRIPTION
This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT) with the speed sensor signal (SPD), the ECM 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.
MONITOR DESCRIPTION
The ECM detects the revolving signal from the transmission revolution sensor (input RPM). The ECM outputs a gearshift signal by comparing the transmission revolution sensor signal with the speed sensor signal (SPD). While the vehicle is operating in the 3rd or 4th gear position in the shift position of D, if the input shaft revolution is less than 300 rpm*1 although the output shaft revolution is more than 1,000 rpm*2, the ECM detects the malfunction, illuminates the MIL and stores the DTC.
*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is 31 mph (50 km/h) or more.
