Code P0717 Mercedes-Benz Description
The P0717 code for Mercedes-Benz indicates a problem with the Input/Turbine Speed Sensor Circuit, specifically that there is no signal being detected. This sensor is responsible for monitoring the speed of the transmission input shaft and turbine shaft. When this sensor fails to provide a signal, it can cause issues with the transmission's shifting patterns, leading to poor performance and potentially causing further damage to the transmission over time. Without a signal from the Input/Turbine Speed Sensor, the vehicle's computer may not be able to accurately control the transmission, resulting in erratic shifting, harsh engagements, or even the transmission going into limp mode to prevent further damage.
Common Causes of P0717 Mercedes-Benz
- Faulty Input/Turbine Speed Sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to the sensor or its connectors
- Transmission fluid contamination affecting sensor performance
- Issues with the transmission control module (TCM)
Symptoms of P0717 Mercedes-Benz
- Delayed or erratic shifting
- Harsh engagement when shifting gears
- Transmission slipping
- Check Engine Light illuminated
- Loss of power or acceleration
How to Fix P0717 Mercedes-Benz
- Begin by diagnosing the issue with a scan tool to confirm the P0717 code and determine the exact cause.
- Inspect the wiring and connectors related to the Input/Turbine Speed Sensor for any damage or corrosion. Repair or replace as necessary.
- Test the sensor itself to ensure it is functioning properly. Replace the sensor if it is faulty.
- Clear the code and test drive the vehicle to confirm that the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the transmission or TCM.
Cost to Fix P0717 Mercedes-Benz
The cost of repairing a P0717 code for a Mercedes-Benz can vary depending on the exact cause of the issue. In general, replacement of the Input/Turbine Speed Sensor itself can range from $100 to $300, while labor costs can add another $100 to $200. If additional wiring repairs or TCM diagnostics are needed, the total repair cost could increase. It is recommended to consult with a certified mechanic or dealership for a more accurate estimate based on your specific vehicle and location.

Frequently Asked Questions about P0717 Mercedes-Benz Code
What does the OBDII code P0717 mean on a Mercedes-Benz?
P0717 indicates that the transmission control module (TCM) has detected no signal from the input/turbine speed sensor, which monitors the rotational speed of the transmission's input shaft.
What are the common symptoms of code P0717 in a Mercedes-Benz?
Symptoms may include harsh or delayed shifting, transmission slipping, reduced fuel efficiency, the vehicle entering limp mode, or the illumination of the check engine light.
What causes the P0717 code to appear in a Mercedes-Benz?
Common causes include a faulty input/turbine speed sensor, damaged or corroded wiring, a failed transmission control module, or mechanical issues within the transmission.
Can I drive my Mercedes-Benz with a P0717 code?
Driving with a P0717 code is not recommended, as it can lead to further transmission damage and may cause unsafe driving conditions due to erratic shifting or limp mode.
How do I diagnose the P0717 code on a Mercedes-Benz?
Diagnosis typically involves using an OBDII scanner to confirm the code, visually inspecting the sensor and wiring for damage, testing the sensor with a multimeter, and checking for transmission fluid contamination.
What is the role of the input/turbine speed sensor in a Mercedes-Benz?
The input/turbine speed sensor monitors the rotational speed of the transmission's input shaft and sends this data to the TCM to ensure proper gear shifting and transmission performance.
How much does it cost to fix a P0717 code on a Mercedes-Benz?
Repair costs can vary, but replacing the input/turbine speed sensor typically costs $200–$400, including parts and labor. Additional costs may arise if wiring or the TCM needs repair or replacement.
Can low transmission fluid cause a P0717 code?
Yes, low or contaminated transmission fluid can affect the input/turbine speed sensor's operation and contribute to the P0717 code. Always check and maintain proper fluid levels.
How do I fix the P0717 code on my Mercedes-Benz?
Repairs may include replacing the input/turbine speed sensor, repairing or replacing damaged wiring, cleaning electrical connectors, updating or reprogramming the TCM, or addressing internal transmission issues.
Is a P0717 code covered under warranty for a Mercedes-Benz?
If your vehicle is still under the powertrain or transmission warranty, repairs related to the P0717 code may be covered. Check with your dealer for warranty specifics.
