Common causes include a faulty steering angle sensor, damaged wiring, and calibration issues. Repair costs can vary based on the specific issue, but replacing the sensor typically ranges from $150 to $300, depending on labor and parts.
Can I drive my car with C068B or should I stop immediately?
While you may still be able to drive your vehicle, it’s not advisable to do so for an extended period. Ignoring the C068B code can lead to worsening handling issues and increased risk of accidents, particularly in slippery conditions. It’s best to address the problem promptly.
How can I diagnose C068B myself using GeekOBD APP?
You can use the GeekOBD APP to scan for trouble codes, which will provide you with specific diagnostic information about the steering angle sensor. The app allows you to view freeze frame data and monitor real-time sensor readings, helping you identify whether the sensor or its connections are faulty.
What vehicles are most commonly affected by C068B?
C068B is frequently reported in various Chevrolet models, particularly those from 2015 to 2020, including the Chevrolet Malibu and Chevrolet Equinox. If you own one of these vehicles, it's important to be vigilant for symptoms associated with this code.
How can I prevent C068B from happening again?
Regular maintenance of your vehicle's electrical systems, including checking wiring and connections, can help prevent C068B. Ensure that any work performed on the steering system is followed by proper calibration of the steering angle sensor to avoid future issues.
What is C068B?
The Diagnostic Trouble Code (DTC) C068B refers specifically to a malfunction related to the steering angle sensor in vehicles, particularly prevalent in certain Chevrolet models from 2015 to 2020. This code indicates that the vehicle's On-Board Diagnostics II (OBD2) system has detected an issue with the steering angle sensor, which is crucial for various vehicle dynamics, including stability control and traction control systems. When this sensor fails, it can lead to incorrect readings, causing the vehicle to behave unpredictably, especially during cornering or slippery conditions. Real-world implications of a C068B code include potential difficulties in steering responsiveness and increased wear on tires due to improper alignment. If ignored, it could lead to more serious issues, including compromised safety features, amplifying the risk of accidents. For drivers, a lit dashboard warning light or a noticeable change in handling can be early indicators of this problem. Addressing this code promptly is essential for maintaining vehicle performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C068B is present:
- The 'Check Engine' light illuminates on the dashboard, indicating a fault in the steering system.
- Inconsistent steering response can be felt, with the steering wheel not aligning properly after turns.
- Drivers may experience traction control or stability control system warnings, which can illuminate dashboard lights.
- Difficulty in executing smooth turns, as the vehicle may feel unresponsive or oversteer.
- Increased tire wear and misalignment due to inaccurate steering input readings.
Possible Causes
Most common causes of C068B (ordered by frequency):
- The most common cause is a faulty steering angle sensor, occurring in about 60% of cases, usually due to wear and tear.
- Another prevalent cause could be damaged wiring or connectors, which can result in intermittent readings; approximately 25% of cases fall into this category.
- Poor calibration of the sensor after previous repairs or steering column work can also lead to this code, making up about 10% of instances.
- Less common but serious causes include a malfunctioning Electronic Control Unit (ECU) that misinterprets sensor data.
- Rarely, this code may appear due to software glitches that require a simple reset or update to the vehicle's firmware.
