P0317 is an OBD2 generic trouble code indicating that the powertrain control module (PCM) has detected a signal from the Rough Road Sensor (RRS) indicating that hardware necessary for proper functionality is not present. This code is triggered when the vehicle’s system doesn’t detect the required hardware for rough road detection.
What Does P0317 Code Mean?
DTC P0317 is a diagnostic trouble code associated with the Rough Road Sensor (RRS) in a vehicle. This code serves as an indicator that the necessary hardware for detecting rough road conditions is not present or not functioning correctly. The Rough Road Sensor plays a crucial role in adjusting various vehicle parameters, such as the transmission shift strategy and the operation of stability control systems, based on road conditions. When P0317 is triggered, it suggests there’s an issue with the sensor or the absence of essential hardware for reliable rough road detection.
Causes of P0317 Trouble Code:
Several factors can contribute to the P0317 code:
- Faulty Rough Road Sensor (RRS): The sensor may be malfunctioning, providing inaccurate signals or not functioning at all.
- Wiring or Connector Issues: Problems in the wiring or connectors associated with the Rough Road Sensor circuit.
- Missing or Inoperative Hardware: Essential components required for rough road detection may be absent or not functioning properly.
- RRS Calibration Issues: Calibration problems with the Rough Road Sensor affecting its ability to detect road conditions accurately.
Symptoms of DTC P0317:
When confronted with Diagnostic Trouble Code P0317, symptoms may include:
- Check Engine Light Illumination: The activation of the check engine light on the dashboard, signaling an issue with the Rough Road Sensor or its required hardware.
- Transmission Shift Irregularities: The transmission may exhibit irregular shifting patterns due to the absence of proper rough road detection.
- Stability Control System Errors: Systems relying on rough road information may not function optimally, impacting vehicle stability.
How to Diagnose DTC P0317:
Effectively diagnosing and addressing the P0317 code involves the following steps:
- Use OBD2 Scanner: Retrieve the code and gather additional information about the Rough Road Sensor issue or missing hardware.
- Inspect Rough Road Sensor: Check the Rough Road Sensor for any damage, malfunctions, or missing components. Replace if necessary.
- Check Wiring and Connectors: Inspect the wiring and connectors associated with the Rough Road Sensor for damage, issues, or poor connections.
- Verify Presence of Required Hardware: Ensure that all components necessary for rough road detection are present and functioning correctly.
- RRS Calibration Check: Perform diagnostics to verify the calibration of the Rough Road Sensor and recalibrate if needed.
How to Fix the P0317 Code:
Addressing DTC P0317 involves specific actions:
- Replace Faulty Rough Road Sensor: If the sensor is malfunctioning, replace it with a new, functioning unit.
- Repair or Replace Damaged Wiring/Connectors: If issues or poor connections are found in the wiring or connectors, repair or replace as needed.
- Ensure Presence of Required Hardware: Confirm that all necessary components for rough road detection are present and functioning.
- RRS Calibration: Calibrate the Rough Road Sensor according to manufacturer specifications to ensure accurate detection.
- Clear DTC: Use the OBD-II scanner to clear the trouble codes after completing repairs.
Adhere to manufacturer guidelines and recommendations during the repair process for effective resolution.
In conclusion, when faced with the P0317 Rough Road Hardware Not Present code, understanding its implications and taking prompt action is crucial.
