Can I drive my car with C0688 or should I stop immediately?
Driving with a C0688 code is not recommended, as it can lead to compromised steering control and increased risk of accidents. If this code appears, it’s advisable to have your vehicle inspected as soon as possible to ensure safety.
How can I diagnose C0688 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the C0688 code and related data. Follow the app's instructions to view live data and check for any irregularities in the sensor readings, which can guide you in diagnosing the issue.
What vehicles are most commonly affected by C0688?
DTC C0688 is commonly found in vehicles like the 2013-2016 Dodge Dart, Chrysler 200, and Jeep Cherokee models. Always check for any recalls or Technical Service Bulletins (TSBs) related to steering systems for your specific make and model.
How can I prevent C0688 from happening again?
Regular maintenance of your vehicle’s steering system, including checking for loose connections and ensuring proper alignment, can help prevent C0688. Additionally, avoid aggressive driving that could stress the steering components and always address any warning lights promptly.
What is C0688?
The DTC C0688 code indicates a problem with the steering angle sensor calibration in your vehicle. This sensor is crucial for systems such as electronic stability control (ESC) and traction control, as it helps monitor the position and movement of the steering wheel. When the steering angle sensor is not calibrated correctly, it sends incorrect data to the vehicle's computer, leading to potential handling issues and loss of control. This issue is commonly found in vehicles like the 2013-2016 Dodge Dart and other models that incorporate similar safety systems. If you encounter this code, you may notice that your check engine light is illuminated, and your vehicle may exhibit erratic handling characteristics. Ignoring this code can lead to more severe problems, including compromised safety features that are designed to keep you on the road safely. In some cases, you might also experience a decrease in fuel efficiency or the vehicle entering limp mode, which reduces power to prevent further damage. Addressing this code promptly is essential for maintaining vehicle stability and ensuring your safety while driving.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0688 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs attention.
- Steering feels unresponsive or loose, making it difficult to control the vehicle, especially during sharp turns.
- The electronic stability control warning light may activate, suggesting that the stability system is compromised.
- Vehicle may enter limp mode, limiting power and speed to prevent further damage.
- Increased fuel consumption by approximately 10% due to improper sensor readings affecting engine performance.
Possible Causes
Most common causes of C0688 (ordered by frequency):
- The most common cause is a misalignment of the steering angle sensor, occurring in about 60% of cases, often due to a recent steering wheel adjustment or suspension work.
- Another common cause is a faulty steering angle sensor itself, which can lead to incorrect data being sent to the vehicle’s computer.
- A third cause might be corroded wiring or loose connections, which can disrupt the communication between the sensor and the vehicle's computer.
- Less common but serious causes include a malfunctioning electronic control module (ECM) that may require replacement.
- A rare but possible cause is physical damage to the steering column or sensor due to an accident or improper repairs.
