This summary uses the existing diagnostic information shown in full below.
The car's computer is looking for a special sensor that tells it when the car is driving on a bumpy road, but it can't find it.
The vehicle's computer system is unable to detect the rough road sensor, which is used to adjust engine and transmission behavior on uneven surfaces.
The P0317 code indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected that the rough road detection hardware, which usually includes sensors like the wheel speed sensor, is not present or not functioning. This system helps the vehicle adjust its performance when driving on uneven or rough surfaces.
• Check Engine Light is on
• Possible rough engine performance on uneven roads
• Transmission may not shift properly
• Missing or faulty rough road sensor
• Damaged wiring or connectors
• Faulty ECM/PCM
ECM: Engine Control Module
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Check for the presence of the rough road sensor
• Inspect wiring and connectors for damage
• Test the ECM/PCM for faults
• Install or replace the rough road sensor
• Repair or replace damaged wiring or connectors
• Replace or reprogram the ECM/PCM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular inspection of sensors and wiring
• Avoid driving on extremely rough terrain
• Keep vehicle maintenance up to date
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid driving on rough roads until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on sensors and ECM/PCM.
This code is relatively uncommon and typically appears in vehicles equipped with advanced traction and stability control systems.
Moderate – The vehicle can still be driven, but performance may be affected, especially on rough roads.
Ignoring this code may lead to decreased vehicle performance and handling on rough terrain, which could be a safety concern.
• Vehicle driven on a rough or uneven surface
• Engine running and vehicle in motion
The rough road sensor is typically located near the wheel hubs or integrated with the ABS sensors.
Q: Can I drive with a P0317 code?
A: Yes, but be cautious on rough roads as vehicle performance may be affected.
Q: Does this code affect fuel efficiency?
A: Not directly, but improper engine or transmission response could lead to inefficiencies.
Pro · Four-system diagnostics
A handheld scanner aimed at engine, transmission, ABS, and airbag diagnostic work.
Chassis and ABS faults usually need a scanner that can read brake-system data directly.
