Problem verification:

Problem verification
?1.
Turn the vehicle to the ON mode.

?2.
Clear the DTC with the HDS.


?3.
Turn the vehicle to the OFF (LOCK) mode.

?4.
Raise the vehicle on a lift. Make sure it is securely supported, and allow all four wheels to rotate freely.

?5.
Start the engine.

?6.
Disable the VSA by pressing the VSA OFF button (with VSA).

?7.
Test-drive the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down, and stop the wheels.

?8.
Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0717 indicated?

     
YES
     
     
     
The failure is duplicated. Go to step 2.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the torque converter turbine speed sensor and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
2.
Determine possible failure area (NT line, others):

Determine possible failure area (NT line, others)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Disconnect the following connector.
Torque converter turbine speed sensor 3P connector

?3.
Turn the vehicle to the ON mode.

?4.
Measure the voltage between test points 1 and 2.

?1.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
Torque converter turbine speed sensor 3P connector: disconnected
Test point 1
Torque converter turbine speed sensor 3P connector No. 1
Test point 2
Torque converter turbine speed sensor 3P connector No. 3


Is there about 5 V?

     
YES
     
     
     
     
NO
     
     
     
The torque converter turbine speed sensor is OK. Repair an open in the SG2 wire between the torque converter turbine speed sensor and the PCM.?
5.
Shorted wire check (NT line):

Shorted wire check (NT line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS.


?3.
Disconnect the following connector.
PCM connector C (51P)

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Torque converter turbine speed sensor 3P connector: disconnected
 
PCM connector C (51P): disconnected
Test point 1
Torque converter turbine speed sensor 3P connector No. 2
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short to ground in the NT wire between the torque converter turbine speed sensor and the PCM.?
     
NO
     
     
     
The NT wire is not shorted. Go to step 6.
6.
Open wire check (NT line):

Open wire check (NT line)
?1.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Torque converter turbine speed sensor 3P connector: disconnected
 
PCM connector C (51P): disconnected
Test point 1
Torque converter turbine speed sensor 3P connector No. 2
Test point 2
PCM connector C (51P) No. 33


Is there continuity?

     
YES
     
     
     
The NT wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0717 goes away and the PCM was updated, troubleshooting is complete. If DTC P0717 goes away and the PCM was substituted, replace the original PCM.?
     
NO
     
     
     
Repair an open in the NT wire between the torque converter turbine speed sensor and the PCM.?
