The P0319 OBD-II code is associated with the Rough Road Sensor “B” Signal Circuit. This code indicates that the vehicle’s onboard diagnostics have detected an issue related to the rough road sensor, which helps the engine control module (PCM) determine whether the vehicle is experiencing engine problems or is simply driving on a rough road.
What Does the P0319 Code Mean?
The P0319 code is set when the PCM cannot distinguish between a potential engine issue and the effects of driving on a rough road. Essentially, it means that the system is receiving conflicting signals regarding the condition of the vehicle and its environment.
What Causes the P0319 Code?
Several factors can lead to the P0319 code being triggered, including:
- Crankshaft Position Sensor (CKP) failure
- Electronic Brake Control Module (EBCM) failure
- Powertrain Control Module (PCM) failure
- Wiring issues related to the sensor
What Are the Symptoms of the P0319 Code?
Drivers may experience various symptoms when the P0319 code is present, including:
- Potential performance issues with the engine
- Illumination of the Check Engine Light
- Unusual engine behavior that may mimic rough road conditions
How Serious Is the P0319 Code?
The P0319 code is categorized as a moderate severity code. While it may not pose an immediate threat to the vehicle’s safety or functionality, it is important to have it diagnosed in a timely manner. Ignoring this code could lead to more serious problems down the road.
How to Diagnose the P0319 Code
Diagnosing the P0319 code typically involves the following steps:
- Use an OBD-II scanner to confirm the P0319 code and check for any additional codes.
- Inspect the wiring and connectors associated with the rough road sensor for damage or corrosion.
- Test the Crankshaft Position Sensor (CKP) and the Electronic Brake Control Module (EBCM) for proper functionality.
- Evaluate the Powertrain Control Module (PCM) to rule out any internal failures.
Common Repairs for the P0319 Code
Some common repairs needed for the P0319 code include:
- Replacement of the Crankshaft Position Sensor
- Repair or replacement of damaged wiring or connectors
- Replacement of the Electronic Brake Control Module (EBCM) if it is found to be faulty
- Diagnosis and potential replacement of the Powertrain Control Module (PCM)
How Much Does It Cost to Fix the P0319 Code?
The cost to fix the P0319 code can vary widely depending on the underlying cause. Basic repairs, such as replacing the crankshaft position sensor, can cost anywhere from $150 to $400. More complex repairs involving the PCM or wiring issues can lead to costs ranging from $500 to $1,500 or more.
Can I Fix the P0319 Code Myself?
While some DIY enthusiasts may be able to handle basic repairs, such as replacing a sensor, diagnosing the P0319 code often requires specialized equipment and expertise. If you are not experienced with automotive diagnostics and repairs, it is advisable to consult a professional mechanic to ensure the issue is addressed correctly.
