P0717

DTC P0717 Turbine Speed Sensor Circuit No Signal

DESCRIPTION
This sensor detects the rotation speed of the turbine, which shows the input revolution of the transmission. By comparing the input speed signal (NT) with the counter gear speed sensor signal (SP2), the ECM detects the shift timing of the gears and controls the engine torque and hydraulic pressure according to various conditions. As a result, smooth gear shifting is achieved.

P0717:

1. Reference: Inspect using an oscilloscope. Check the waveform of the ECM connector.

MONITOR DESCRIPTION
This DTC indicates that a pulse is not output from the speed sensor NT (input speed sensor) or is output only a little. The NT terminal of the ECM detects the revolving signal from the speed sensor (NT) (input RPM). The ECM outputs a gear shift signal comparing the input speed sensor (NT) with the output speed sensor (SP2).

While the vehicle is operating in the 4th, 5th or 6th gear position with the shift lever on D, if the input shaft revolution is less than 300 rpm*1 and the output shaft revolution is 1,000 rpm or more*2, the ECM detects the trouble, illuminates the MIL and stores the DTC.

HINT:
*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is approximately 50 km/h (31 mph) or more.

INSPECTION PROCEDURE

HINT: Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTICE: In the table, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
4. Turn the ignition switch ON.
5. Turn the intelligent tester ON.
6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
7. Follow the instructions on the tester and read the DATA LIST.

ECM:

HINT:
^ SPD (NT) is always 0 rpm while driving:
Open or short in the sensor or circuit.
^ SPD (NT) is always more than 0 rpm and less than 300 rpm while driving the vehicle at 50 km/h (31 mph) or more:
Sensor trouble, improper installation, or intermittent connection trouble of the circuit.
