DTC P0717 (CVT (ECM/Pcm))

DTC P0717  : CVT Input Shaft (Drive Pulley) Speed Sensor A Circuit No Signal / Input/Turbine Speed Sensor A Circuit No Signal

NOTE: 

• Before you troubleshoot, review the General Troubleshooting Information .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC (CVT)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Raise the vehicle on a lift. Make sure it is securely supported, and allow the front wheels to rotate freely.

   -4. Start the engine.

   -5. Enter the VSA maintenance mode .

   -6. Test-drive the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down, and stop the wheels.

   -7. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   P0717 CVT Input Shaft (Drive Pulley) Speed Sensor A Circuit No Signal / Input/Turbine Speed Sensor A Circuit No Signal

   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 or 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)

   -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.

   Is there about 5 V?

   YES 

   Go to step 3.

   NO 

   Go to step 5.

3. Open wire check (VCC2 line)

   -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 (female terminals) No. 3 :
   Test point 2	Body ground

   Is there about 5 V?

   YES 

   Go to step 4.

   NO 

   Repair an open in the VCC2 wire between the torque converter turbine speed sensor and the PCM.

4. Torque converter turbine speed sensor check

   -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 (female terminals) No. 1 :
   Test point 2	Torque converter turbine speed sensor 3P connector (female terminals) No. 3 :

   Is there about 5 V?

   YES 

   Replace the torque converter turbine speed sensor .

   NO 

   Repair an open in the SG2 wire between the torque converter turbine speed sensor and the PCM.

5. Shorted wire check (NT line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Jump the SCS line with the HDS, and wait more than 1 minute.

   NOTE:  This step must be done to protect the PCM from damage.

   -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 (female terminals) No. 2 :
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short to body 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)

   -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 (female terminals) No. 2 :
   Test point 2	PCM connector C (51P) No. 21

   Courtesy of HONDA, U.S.A., INC.

   Is there continuity?

   YES 

   The NT wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or replace the original PCM .

   NO 

   Repair an open in the NT wire between the torque converter turbine speed sensor and the PCM.
