P0317 OBD-II Trouble Code: Rough Road Hardware Not Present

check engine light

P0317 code definition

The P0317 code means that the PCM has indicated that rough road hardware is not present.

What the P0317 code means

When the P0317 code is present, the powertrain control module has found a variation in the crankshaft position. The vehicle’s computer believes that the reason is because the road conditions are rough or uneven. When the crankshaft position moves in an unexpected manner because of the road conditions, it will often store the code. In some cases, it will require multiple failure cycles before the code causes the Check Engine Lamp to come on.

What causes the P0317 code?

The following are the most common causes of the P0317 code:

  • Missing road sensors
  • Defective road sensors
  • Disconnected road sensors

What are the symptoms of the P0317 code?

The stored trouble code could cause a malfunction indicator lamp to light up. In some cases, there can also be issues with the vehicle’s traction control or the antilock brake systems. In addition, there may be engine misfires.

How does a mechanic diagnose the P0317 code?

The mechanic will utilize an OBD-II scanner to help them with the diagnosis. It is easy to overlook issues when there is an isolated misfire of the engine or crankshaft inconsistency. The scanner will help the mechanic determine the actual problem. They will then reset the code and test drive the vehicle. They do this so they can see if the code returns. If it does, they know that there is an issue that they need to investigate further.

Common mistakes when diagnosing the P0317 code

The most common mistakes when diagnosing the P0317 code are replacing certain parts unnecessarily. They might replace the wheel speed sensors, the crankshaft position sensors, or the camshaft when those parts do not need to be replaced.

How serious is the P0317 code?

While it might not seem serious, it actually can be a big problem. In addition to the engine misfires, there could also be issues with the traction control as well as the antilock brake system. These are extremely important elements of your vehicle, and you do not want to have anything go wrong with them. Make sure you take the vehicle to a qualified mechanic who can check the vehicle and make the proper repairs.

What repairs can fix the P0317 code?

The following are some of the repairs that the mechanics might employ when trying to fix the P0317 code.

  • After the OBD-II diagnosis, the mechanic will visually inspect all of the wiring and connections.
  • If any of the connections have been damaged, disconnected, corroded, or shorted, the mechanic will make the repairs and replacements.
  • They will then retest the vehicle.

Additional comments for consideration regarding the P0317 code

You don’t want to have any issues with your vehicle, even if they might seem small or if you don’t notice any difference in performance with your car or truck. When you have any trouble codes showing up on your vehicle, it is important to take them to a qualified mechanic as soon as you are able. They can test the vehicle, find out what’s wrong with it, and take care of the repairs for you.
