What Does P0717 Trouble Code Mean?
The P0717 trouble code indicates a problem with the input/turbine speed sensor circuit in your vehicle.
This sensor monitors the rotational speed of the turbine shaft in the transmission. The data it collects is essential for the transmission control module (TCM) to manage gear shifts and overall transmission performance.
When the P0717 code is triggered, it means that the TCM is not receiving a signal from the input/turbine speed sensor.
This lack of signal can disrupt the transmission’s ability to operate smoothly and efficiently.
Essentially, the TCM doesn’t know how fast the turbine shaft is spinning, which leads to various transmission issues.
Several problems can arise from this code. You might notice that your transmission is slipping, or you could experience erratic shifting.
In some cases, the transmission might not shift at all. These symptoms can make your vehicle difficult or unsafe to drive.
A faulty input/turbine speed sensor, damaged wiring, or a malfunctioning TCM often cause the P0717 code.
The sensor itself might be defective, or there could be an issue with the connections or wiring leading to it. In some cases, internal transmission problems can also trigger this code.
Addressing the P0717 code promptly is important because it can affect your vehicle’s drivability and lead to more severe transmission damage if ignored.
Understanding the exact meaning of the P0717 trouble code is the first step toward diagnosing and fixing the issue, ensuring your transmission operates smoothly again.
P0717 Trouble Code Symptoms
When the P0717 trouble code is present, you may notice several symptoms affecting your vehicle’s performance:
- Transmission slipping
- Erratic or harsh shifting
- Transmission not shifting at all
- Delayed engagement when shifting from park to drive
- Illuminated check engine light
- Reduced fuel efficiency
- Vehicle entering “limp” mode
P0717 Trouble Code Causes
The P0717 trouble code can be triggered by several underlying issues:
- Faulty input/turbine speed sensor
- Damaged or corroded sensor wiring or connectors
- Malfunctioning transmission control module (TCM)
- Internal transmission problems
- Electrical short or open circuit in the sensor circuit
- Faulty engine control module (ECM)
How To Fix A P0717 Trouble Code
Fixing a P0717 trouble code involves diagnosing the exact cause and then addressing it. Here’s a step-by-step guide to help you through the process:
1. Check for Additional Codes
Use an OBD-II scanner to check for other trouble codes that might be present. This can provide more context and help narrow down the issue.
2. Inspect the Sensor and Wiring
Visually inspect the input/turbine speed sensor and its wiring. Look for signs of damage, corrosion, or loose connections. If you find any issues, repair or replace the damaged parts.
3. Test the Sensor
Use a multimeter to test the input/turbine speed sensor. Compare the readings to the manufacturer’s specifications. If the sensor is out of range, replace it.
4. Check the Connectors
Ensure all connectors are clean and secure. Corroded or loose connectors can disrupt the signal between the sensor and the TCM.
5. Inspect the TCM and ECM
If the sensor and wiring are in good condition, the issue might be with the transmission control module (TCM) or the engine control module (ECM). These components might need professional testing or replacement.
6. Examine Internal Transmission Components
If other diagnostics fail, there could be an internal transmission issue. This step might require a professional mechanic, as it involves a more in-depth inspection and repair.
7. Clear the Codes and Test Drive
After making repairs, clear the trouble codes with your OBD-II scanner. Take your vehicle for a test drive to ensure the issue is resolved. Monitor for any reappearance of the check engine light.
Addressing a P0717 trouble code promptly can prevent further transmission damage and improve your vehicle’s drivability. If you’re not comfortable performing these checks and repairs yourself, consult a professional mechanic.
Conclusion
Now you know what the P0717 trouble code means and how to fix it.
From checking the sensor to inspecting the wiring, you’ve got the steps covered.
