Error code P0317 indicates that your vehicle's powertrain control module (PCM) has detected a missing or malfunctioning rough road sensor (sometimes called a road surface detection sensor). This sensor helps the PCM adjust engine and transmission behavior when driving on uneven roads. In most cases, the issue is a disconnected or faulty sensor, but it can also be caused by wiring damage or a software glitch.

If you have inspected the sensor and wiring thoroughly and the code persists, the issue may be internal to the PCM or related to other sensors like ABS wheel speed sensors. Professional diagnosis with advanced scan tools is recommended.

Frequently Asked Questions

Can I drive with error code P0317?
Yes, you can usually drive, but the PCM may not compensate for rough roads, potentially affecting drivability. It's best to fix it soon.
What is a rough road sensor?
It's a sensor that detects rough/uneven road surfaces. It sends data to the PCM to adjust engine and transmission operation for improved control.
Where is the rough road sensor located?
Typically near the vehicle's frame, steering rack, or suspension crossmember. Refer to a service manual for your specific make/model.
Can a bad ABS sensor cause P0317?
In some vehicles, the ABS wheel speed sensors are used to detect rough roads. A faulty ABS sensor can trigger P0317. Check ABS codes too.
How much does it cost to fix P0317?
If DIY, a sensor may cost $30-$100. Labor at a shop could add $100-$200. Diagnosis fees may apply.
