| Circuit/System Description |
The input shaft sensor is a hall-effect type sensor. The input shaft sensor detects revolutions of the intermediate shaft C2 drum. As the C2 drum rotates, the sensor produces a signal frequency based on the machined surface of the C2 drum. This signal is transmitted to the transmission control module (TCM). The TCM uses the input shaft sensor signal in connection with the output speed sensor signal to control engine torque, shift timing, and lock-up.
| Conditions for Running the DTC |
P0717
| • |
The ignition voltage is 10.2-15.5 V.
|
|
| • |
The engine speed is greater than 400 RPM for 2 s.
|
|
| • |
The transmission is not in emergency mode.
|
|
| • |
Driving in D range.
|
|
| • |
Current gear 2nd or higher.
|
|
| • |
TCM communication is normal.
|
|
| • |
Output speed multiplied with current gear ratio is more than 600 RPM.
|
|
| Conditions for Setting the DTC |
P0717
| • |
No input shaft sensor pulse while receiving pulses on the output speed sensor.
|
|
| • |
Deviation from calculated output speed is more than 300 RPM.
|
|
| • |
No input shaft sensor pulse when vehicle speed from ABS is more than 20 km/h (13 MPH) for 300 ms.
|
|
| Action Taken When the DTC Sets |
| • |
DTC P0717 is Type A DTC.
|
|
| • |
The TCM freezes transmission adaptive functions.
|
|
| • |
The TCM turns OFF all solenoids.
|
|
| • |
The TCM allows the vehicle after a stop to operate only in the second gear and “R” range.
|
|
| Conditions for Clearing the DTC |
| • |
DTC P0717 is Type A DTC.
|
|
| • |
Output speed is greater than 300 RPM for more than 70 s.
|
|
| • |
Deviation from calculated output speed is less than 5% for more than 1 s.
|
|
| Diagnostic Aids |
Damage or misalignment of the C2 drum machined teeth surface may cause a speed sensor malfunction.

| Circuit/System Verification |
| 1. |
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
|
|
| 2. |
Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
|
|
| Circuit/System Testing |
Static Test
| 1. |
Ignition OFF, remove the K71 Transmission Control Module.
|
|
| 2. |
Test for more than 1 MΩ between the low reference circuit terminal 13 X2 and the voltage supply circuit terminal 12 X2.
|
|
| 3. |
If less than the specified range, test the wiring harness for internal short. If the circuit tests normal, replace the automatic transmission.
|
|
| 4. |
Test for infinite resistance between each terminal and the low reference circuit terminal 13 X2 and also to the voltage supply circuit terminal 12 X2.
|
|
| 5. |
If less than the specified range, replace the wiring harness.
|
|
| 6. |
If all circuits test normal, test or replace the K71 Transmission Control Module. Verify the DTC does not reset.
|
|
| 7. |
If the DTC resets, replace the automatic transmission.
