P0317 Code: Rough Road Hardware Not Present

The P0317 code means the computer expects a rough road sensor or signal, used to ignore false misfires on bumpy roads, and cannot find it. It does not affect how the engine runs, and you can keep driving. The usual causes are an ABS module that is not communicating or a computer configured wrong after a replacement.

What the P0317 code means

On very rough roads, the vibrations in the crankshaft can look like misfires. Some vehicles use an acceleration sensor or the ABS signal to detect rough roads and pause the misfire monitoring.

The P0317 code means the computer is not receiving that information. It can be an ABS module that is not communicating, a missing sensor, or a computer that was configured wrong after a replacement.

It does not affect engine operation, but it can cause false misfire codes on dirt roads.

P0317 code symptoms

  • Check engine light on.
  • Possible false P0300 codes on rough roads.

Likely causes of the P0317 code

  1. ABS module not communicating.
  2. Rough road sensor missing or unplugged.
  3. Computer with the wrong configuration after it was replaced.

How to diagnose the P0317 code step by step

  1. Check for ABS codes and communication (U) codes.
  2. Check the computer configuration with the scan tool.
  3. Inspect the sensor and its connector if the vehicle has one.

How to fix the P0317 code

  • Repair the communication with the ABS.
  • Configure the computer correctly.
  • Replace the sensor if it is missing or damaged.

Once the signal is back, clear the P0317 code and drive over a rough stretch of road to confirm it does not return.

Technical reference data

  • Many vehicles use the ABS wheel speed signal.
  • These values are for orientation only. Check the manufacturer data for your engine.

Frequently asked questions about P0317

Does it affect the engine?
Not directly. The engine runs normally, but misfire monitoring can be fooled on bumpy roads.
Can I drive with a P0317 code?
Yes. The code does not limit the engine, though you may see false misfire codes on dirt roads.
Why does it appear after replacing the computer?
Because the new computer may be configured for different equipment than your vehicle has.
How much does it cost to fix P0317?
Between $0 and $300 depending on whether it is a configuration, the ABS communication or a sensor.
What does the P0317 code mean?
It is a generic OBD2 code that means the rough road hardware the computer expects is not present or not reporting.
Will a P0317 code clear itself?
Not if the cause is still there. A wrong computer configuration or a missing signal keeps the code coming back until it is corrected.
