Code P0717 Honda Description

The P0717 code for Honda vehicles indicates a problem with the Input/Turbine Speed Sensor 'A' Circuit, specifically that there is no signal being received. This sensor plays a critical role in the transmission system by monitoring the speed of the input shaft and turbine shaft. The information it provides is essential for the transmission control module to determine the proper gear shift points, torque converter lockup, and overall transmission performance. When this sensor fails to send a signal, it can lead to erratic shifting, poor fuel efficiency, and potential transmission damage if left unaddressed.

  • What can cause the d light to blink in dashboard when driving a Honda Accord cl7

    Reply to Comment

  • What year is your Accord?

    The "D" light blinking (flashing) means that there is a transmission malfunction.

    • Replacing the input/turbine speed sensor will it fix the flashing D light the code that came up was a po717

      Reply to Comment

      • Yes, replacing the input/turbine speed sensor can fix the flashing “D” light, especially if the only code showing is P0717. That code means the transmission control module isn’t seeing a signal from the sensor, which it needs to manage shifting.

        The “D” light flashes when the transmission goes into fail-safe mode, usually to protect itself when it can’t determine input speed. Common causes include:

        • A bad input speed sensor (most likely)
        • Broken or corroded wiring to the sensor
        • Faulty connector
        • In rare cases, a bad transmission control module (TCM)

        Start by replacing the sensor—just make sure you’re changing the input speed sensor, not the output one (they’re different but sometimes close together). If the light and code come back afterward, you’ll want to check the wiring and connector next.

        Let me know what model and engine you have—I can help with sensor location if needed.

        • In my Odyssey 2006 I had the code P0722. then i did replace the sensor located on top of the transmission (easier access) but the fault remains. Then I changed the one below the battery. Both sensors look the same (I get them from Auto Zone). Speed indication is back, but alarm remains and new code is P0717. What could it be now?

          Reply to Comment

          • The fact that your speedometer is working again tells me you probably fixed the original P0722 (output speed sensor) issue. However, P0717 is a different fault—it means the PCM is not receiving a signal from the input/turbine speed sensor.

            Since you've already replaced both sensors, I wouldn't assume another bad sensor just yet. The next things I would check are the wiring and connectors to the input speed sensor, especially for damaged wires, corrosion, or terminals that aren't making good contact. Also verify that the replacement sensors are the correct part numbers. Although they may look identical, on some Honda transmissions the input and output sensors are not interchangeable internally.

            If the wiring and connectors check out, a scan tool that displays live data can confirm whether the PCM is seeing the turbine speed signal. If the signal stays at zero while the engine is running and the transmission is in gear, then the problem is likely in the sensor circuit or, less commonly, the PCM. I would diagnose the circuit before replacing any more parts.
