DTC P0715 Input / Turbine Speed Sensor Circuit Malfunction

DTC P0717 Input Speed Sensor Circuit No Signal

DESCRIPTION
The speed sensor (NT) detects the input axis rotation speed and inputs it into the TCM as a signal.

Based on the transmission revolution sensor (NT) signal and the transmission revolution sensor (NC3 and SP2) signal, the TCM controls engine torque and shift timing. Also, based on the input axis rotation speed and the engine rpm signal, lock-up control is performed.

MONITOR DESCRIPTION
The NT terminal of the TCM detects a revolution signal from the speed sensor (NT) (input RPM). The TCM calculates a gearshift comparing the speed sensor (NT) with the speed sensor (SP2).

While the vehicle is operating in 2nd, 3rd, 4th or 5th gear 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 TCM interprets this as a fault, illuminates the MIL and stores the DTC.
*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is 50 km/h (31 mph) or more.

INSPECTION PROCEDURE

HINT: Using the intelligent tester or Techstream 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 engine switch off.
3. Connect the intelligent tester or Techstream to the DLC3.
4. Turn the engine switch on (IG).
5. Turn the tester ON.
6. Enter the following menus:
Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.
Techstream - Select: Powertrain / ECT / Data List.
7. Follow the instructions on the tester and read the DATA LIST.

HINT:
^ SPD (NT) is always 0 while driving: Open or short in the sensor or circuit.
^ SPD (NT) is always more than 0 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.
