P0717 – OBD-II DTC

OBD-II DTC P0717 – Input/Turbine Speed Sensor Circuit Range/Performance

DTC P0717 meaning

DTC P0717 refers to a problem with the Input/Turbine Speed Sensor Circuit. This code indicates that the Engine Control Module (ECM) has detected a range or performance issue with the input or turbine speed sensor, which is responsible for monitoring the rotational speed of the transmission’s input shaft. This information is crucial for the transmission control system to function properly, as it helps determine the appropriate gear selection and shift timing.

DTC P0717 symptoms

Common symptoms associated with DTC P0717 may include:

• Illuminated check engine light
• Transmission slipping or erratic shifting
• Delayed engagement when shifting from park to drive or reverse
• Reduced fuel efficiency
• Unusual engine RPM fluctuations

DTC P0717 causes

Several factors can lead to the triggering of DTC P0717, including:

• Faulty input/turbine speed sensor
• Wiring issues, such as damaged or corroded connectors
• Short circuits or open circuits in the sensor circuit
• Faulty transmission control module (TCM)
• Low transmission fluid levels or fluid contamination

DTC P0717 seriousness

DTC P0717 can be considered serious as it directly affects the transmission’s performance. If left unaddressed, it may lead to further transmission damage, reduced drivability, and potential safety hazards. It is advisable to diagnose and repair the issue promptly to avoid more extensive repairs and ensure safe vehicle operation.

How to diagnose DTC P0717

To diagnose DTC P0717, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P0717 code.
2. Check for any additional trouble codes that may provide more context.
3. Inspect the input/turbine speed sensor and its wiring for visible damage or corrosion.
4. Test the sensor’s resistance and voltage output according to the manufacturer’s specifications.
5. Examine the transmission fluid level and condition, replacing it if necessary.
6. Check the TCM for any faults or issues.

How to fix DTC P0717 step-by-step instructions

To fix DTC P0717, follow these steps:

1. Repair or replace any damaged wiring or connectors related to the input/turbine speed sensor.
2. If the sensor is faulty, replace it with a new one.
3. Ensure the transmission fluid is at the correct level and in good condition replace if needed.
4. Clear the DTC using an OBD-II scanner.
5. Test drive the vehicle to ensure the issue is resolved and the check engine light does not reappear.
