P0717
TX6A AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: P0717; Turbine Speed Sensor Circuit No Signal; 2013 MY FR-S [03/2012 -]
P0717 - Turbine Speed Sensor Circuit No Signal
DESCRIPTION
The transmission revolution sensor (NT) inputs signal into the TCM as a signal of the input axis revolutions.
The TCM carries out shift timing control based upon signals from the transmission revolution sensor (NT) and the transmission revolution sensor (SP2).
MONITOR DESCRIPTION
This DTC indicates that pulse is not output from the transmission revolution sensor (NT) or is output only little. The transmission revolution sensor (NT) terminal of the TCM detects the revolving signal from transmission revolution sensor (NT) (input RPM). The TCM outputs a gearshift signal comparing the transmission revolution sensor (NT) with the transmission revolution sensor (SP2).
While the vehicle is operating in the shift position of D, the output shaft revolution is 550rpm or more*, the TCM detects the trouble, illuminates the MIL and stores the DTC.
*: The engine speed is 400 rpm or more.

1. DATA LIST
HINT
Using the Techstream 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.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / ECT / Data List.
(g) According to the display on the Techstream, 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.
PROCEDURE
1. INSPECT TRANSMISSION REVOLUTION SENSOR (NT) INSTALLATION
(a) Check the transmission revolution sensor (NT) installation.
OK:
The installation bolt is tightened properly and there is no clearance between the sensor and transmission case.
NG -- SECURELY INSTALL TRANSMISSION REVOLUTION SENSOR (NT) OR REPLACE TRANSMISSION REVOLUTION SENSOR (NT)
OK -- Continue to next step.
2. INSPECT TRANSMISSION REVOLUTION SENSOR (NT)
(a) Disconnect the L5 transmission revolution sensor (NT) connector.
(b) Perform inspection of the transmission revolution sensor (NT). Testing and Inspection
(c) Connect the L5 transmission revolution sensor (NT) connector.
NG -- REPLACE TRANSMISSION REVOLUTION SENSOR (NT) Removal
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (TRANSMISSION REVOLUTION SENSOR (NT) - TCM)
(a) Disconnect the A19 TCM connector.
(b) Disconnect the L5 transmission revolution sensor (NT) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
(d) Connect the A19 TCM connector.
(e) Connect the L5 transmission revolution sensor (NT) connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. REPLACE TCM
(a) Replace the TCM Removal.
NEXT -- PERFORM THE RESET MEMORY
