The P0317: Rough Road Hardware Not Present code indicates that the vehicle’s engine control module (ECM) has detected an issue related to the rough road sensor, which is used to detect uneven surfaces and adjust the engine’s performance accordingly. The code can be triggered by a faulty sensor, problems with the sensor circuit, or wiring issues. When this code appears, it means the ECM is not receiving the expected data from the rough road hardware, potentially leading to performance issues, especially on rough terrain.
P0317 – Quick Overview
| Meaning | P0317: Rough Road Hardware Not Present |
| Is it serious? | Yes, this code can be serious as it affects the ECM’s ability to adjust engine performance on rough roads, potentially leading to drivability issues. |
| Possible causes | – Faulty rough road sensor – Sensor circuit issues – Wiring problems |
| How to diagnose? | – Inspect and test rough road sensor – Check sensor circuit and wiring – Verify sensor installation |
P0317 Meaning
The P0317: Rough Road Hardware Not Present code means that the vehicle’s ECM is not receiving input from the rough road sensor, which helps detect uneven surfaces. This could be due to a faulty sensor, an issue with the sensor circuit, or problems with the wiring. Without this sensor, the engine may not adjust properly for rough road conditions, which could lead to a rough driving experience.

Follow these steps to diagnose and resolve the P0317 code by addressing potential causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that may provide further information about the problem. | OBD-II Scanner |
| Inspect the Rough Road Sensor | Visually inspect the rough road sensor for signs of damage or disconnection. Ensure it is securely mounted and functioning properly. | Flashlight, Safety Gloves |
| Test the Rough Road Sensor | Use a multimeter to test the sensor’s resistance and operation. Compare the readings to the manufacturer’s specifications. | Multimeter, Manufacturer’s Specifications |
| Check Sensor Circuit and Wiring | Inspect the wiring and connections related to the rough road sensor for signs of damage, corrosion, or disconnections. Repair as needed. | Flashlight, Wiring Repair Kit |
| Verify Sensor Installation | Ensure that the rough road sensor is properly installed and mounted in the correct location according to the manufacturer’s guidelines. | Vehicle Owner’s Manual, Safety Gloves |
| Clear the Code and Test Drive | After completing the necessary repairs, clear the P0317 code using the OBD-II scanner. Test drive the vehicle to ensure the problem is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0317 code has not returned. If the code reappears, further diagnosis may be required. | OBD-II Scanner |
This guide provides a systematic approach to diagnosing and repairing the P0317 code, ensuring that your vehicle’s rough road hardware is functioning properly.
