The OBD-II code P0317 stands for "Rough Road Hardware Not Present." This code is triggered when the vehicle's Powertrain Control Module (PCM) detects that the rough road hardware, which helps the PCM differentiate between engine issues and rough road conditions, is missing or malfunctioning.
Failed Rough Road Sensor: The sensor itself may be defective or damaged.
Misplaced Road Sensor: The sensor might be improperly installed or dislodged.
Faulty Crankshaft Position Sensor: Issues with this sensor can mimic rough road conditions.
Failed Electronic Brake Control Module (EBCM): Malfunctions in the EBCM can trigger the P0317 code.
Defective Powertrain Control Module (PCM): A faulty PCM can misinterpret signals.
Wiring/Electrical Defects: Damaged or corroded wiring can lead to sensor failures.
Control Unit Configuration: The control unit may need to be reconfigured to recognize new or replaced sensors.
Case Study: A vehicle with a dislodged rough road sensor due to improper installation triggered the P0317 code.
Technical Reports: Reports from mechanics indicating frequent issues with the EBCM leading to the P0317 code.

OBD-II code P0317 stands for "Rough Road Hardware Not Present." It indicates that the vehicle's Powertrain Control Module (PCM) has detected that the rough road hardware, which helps differentiate between engine issues and rough road conditions, is missing or malfunctioning.
Common symptoms include engine misfires, rough idling, and decreased fuel efficiency.
The P0317 code can be triggered by a failed rough road sensor, misplaced road sensor, faulty crankshaft position sensor, failed electronic brake control module (EBCM), defective powertrain control module (PCM), or wiring/electrical defects.
The P0317 code is not immediately serious but should be monitored and addressed to prevent potential worsening of the issue.
The P0317 code can be diagnosed using an OBD-II scanner to check for related codes, inspecting the rough road sensor and wiring, and testing the crankshaft position sensor, EBCM, and PCM.
Repair options include replacing the faulty rough road sensor, properly reinstalling a misplaced sensor, inspecting and replacing the crankshaft position sensor, diagnosing and repairing or replacing the EBCM, reprogramming or replacing the PCM, and fixing any damaged or corroded wiring.
While it is possible to drive with the P0317 code, it is advisable to have the issue checked and repaired to avoid potential performance and safety issues.
The cost to fix the P0317 code can vary depending on the specific cause and the vehicle model, but it generally ranges from $100 to $500 for parts and labor.
Yes, regular maintenance checks for sensors and electronic modules, ensuring proper installation, and protecting sensors and wiring from harsh environmental conditions can help prevent the P0317 code.
It is recommended to use high-quality, OEM parts for replacements to ensure compatibility and reliability, although aftermarket parts may be a cost-effective alternative if they meet quality standards.
