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

NOTE: 

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      

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 all four wheels to rotate freely.

    -4. Enter the VSA maintenance mode .

    -5. Run the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.

    -6. 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 and loose terminals between the torque converter turbine speed sensor and the TCM. 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/onboard 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.

    Test condition Vehicle ON mode

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

    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 

    The VCC2 wire is OK. Go to step 4.

    NO 

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

  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 

    The torque converter turbine speed sensor is OK. Repair an open in the SG2 wire between the torque converter turbine speed sensor and the TCM.

  5. Shorted wire check (NT line)

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

    -2. Disconnect the following connector.

    TCM 50P connector

    -3. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      Torque converter turbine speed sensor 3P connector: disconnected
      TCM 50P connector: disconnected
    Test point 1 Torque converter turbine speed sensor 3P connector (female terminals) No. 2 :
    Test point 2 Body ground
    GHH389927Courtesy of HONDA, U.S.A., INC.

    Is there continuity?

    YES 

    Repair a short to ground in the NT wire between the torque converter turbine speed sensor and the TCM.

    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
      TCM 50P connector: disconnected
    Test point 1 Torque converter turbine speed sensor 3P connector (female terminals) No. 2 :
    Test point 2 TCM 50P connector No. 49
    GHH389929Courtesy 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 substitute a known-good TCM , then recheck. If this DTC goes away and the TCM was substituted, replace the original TCM .

    NO 

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