OBD-II Code P0317 is defined as Rough Road Hardware not Present. This code indicates that the engine control module (PCM) is unable to determine whether an issue exists with the engine or if the vehicle is being driven on a rough road.
What Does the P0317 Code Mean?
The P0317 code means that the PCM has detected a situation where it cannot determine if the engine is facing a fault or if it is just the road conditions that are causing the issue. This ambiguity leads to the setting of this code.
What Causes the P0317 Code?
- Failure of the Crankshaft Position Sensor (CKP)
- Failure of the Electronic Brake Control Module (EBCM)
- Failure of the Powertrain Control Module (PCM)
- Wiring issues related to the sensors
What Are the Symptoms of the P0317 Code?
Symptoms of the P0317 code may include:
- Check Engine Light illuminated
- Unusual engine behavior or performance issues
- Possible stalling or rough idling
How Serious Is the P0317 Code?
The P0317 code is considered to have a moderate severity. While it may not pose an immediate threat to vehicle safety or functionality, it is crucial to have it diagnosed promptly. Ignoring this code could lead to more serious engine problems down the line.
How to Diagnose the P0317 Code
Diagnosing the P0317 code involves:
- Using an OBD-II scanner to confirm the P0317 code is present.
- Checking for any other related codes that could provide additional context.
- Inspecting the Crankshaft Position Sensor and associated wiring for damage or disconnections.
- Testing the Electronic Brake Control Module and Powertrain Control Module for proper functionality.
Common Repairs for the P0317 Code
- Replacement of the Crankshaft Position Sensor
- Repair of wiring issues or connections
- Replacement of the Electronic Brake Control Module or Powertrain Control Module if found faulty
How Much Does It Cost to Fix the P0317 Code?
The cost to repair the P0317 code can vary widely based on the underlying issue. Generally, replacing a crankshaft position sensor can range from $100 to $300, while more complex repairs involving the PCM or EBCM may cost significantly more, ranging from $300 to $1,200 or higher depending on labor and parts.
Can I Fix the P0317 Code Myself?
While some DIY enthusiasts may be able to replace a crankshaft position sensor or inspect wiring, it is recommended to consult with a professional mechanic for a thorough diagnosis and repair. Proper tools and diagnostic equipment are often required to accurately assess and resolve the issue.
