DTC P0717 Input Speed Sensor Circuit No Signal


DESCRIPTION

This sensor detects the rotation speed of the turbine, which shows the input revolution of the transaxle. By comparing the input speed signal (NT) with the counter gear speed sensor signal (NC), 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.

DTC No.
DTC Detection Condition
Trouble Area
P0717
ECM detects conditions (a), (b) and (c) continuously for 5 sec. or more (1 trip detection logic):
(a) Vehicle speed: 50 km/h (31 mph) or more
(b) Park/Neutral position switch NSW, R and L is OFF
(c) Speed sensor NT: Less than 300 rpm
  1. Open or short in speed sensor NT circuit
  2. Speed sensor NT
  3. ECM

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 (NC).
While the vehicle is operating in the 2nd, 3rd, 4th or 5th 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 to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTICE:
In the table below, 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 DLC3.
  4. Turn the ignition switch ON and turn the tester ON.
  5. Enter the following menus: Powertrain / Engine and ECT / Data List.
  6. Follow the instructions on the tester and read the Data List.

Measurement Item/Range
Normal Condition
Diagnostic Note
SPD (NT)
Input turbine speed/
Min.: 0 rpm
Max.: 12,750 rpm
  1. Lock-up ON (after warming up engine):
    Input turbine speed (NT) is equal to engine speed.
  2. Lock-up OFF (idling with shift lever on N):
    Input turbine speed (NT) is nearly equal to engine speed.
Data is displayed in increments of 50 rpm
HINT:
  1. SPD (NT) is always 0 rpm while driving:
    Open or short in the sensor or circuit.
  2. 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.
1.INSPECT SPEED SENSOR (INSTALLATION)

  1. Check the speed sensor NT installation.

    OK:
    Installation bolt is tightened properly and there is no clearance between the sensor and transaxle case.
