Regular maintenance is key. Ensure your vehicle’s electrical systems are inspected routinely, and keep an eye on any warning lights. Address any steering or suspension issues promptly to prevent wear on the steering angle sensor.
What is B0C67?
The diagnostic trouble code (DTC) B0C67 refers to a problem with the steering angle sensor in vehicles, particularly prevalent in certain Chevrolet and GMC models from 2016 to 2020. This code indicates that the steering angle sensor, which is critical for stability control and advanced driver-assistance systems (ADAS), is reporting an implausible signal or has failed altogether. Understanding this code is essential because the steering angle sensor helps the vehicle’s computer determine the position of the steering wheel in relation to the vehicle's direction. A malfunction can lead to issues like loss of traction control, problems with lane-keeping assist, and possibly increased wear on the tires due to improper alignment. Common symptoms include an illuminated warning light on the dashboard, erratic steering behavior, and decreased vehicle stability during turns. Ignoring the B0C67 code can result in a significant compromise in safety and vehicle performance, making it crucial for car owners to address this issue promptly.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0C67 is present:
- The check engine light or stability control warning light illuminates on the dashboard, indicating a potential issue with the steering system.
- Drivers may experience unresponsive steering or steering that feels loose, leading to difficulty in maintaining a straight path.
- There might be a noticeable decrease in fuel economy due to the vehicle's computer compensating for the incorrect steering angle data.
- The vehicle might struggle with traction control during slippery conditions, making it harder to maintain control.
- In some cases, the steering wheel may not return to the center position after a turn, leading to further driving difficulties.
Possible Causes
Most common causes of B0C67 (ordered by frequency):
- The most common cause of B0C67 is a faulty steering angle sensor, which occurs in approximately 60% of cases. This sensor can wear out over time or fail due to exposure to moisture.
- Another frequent cause is damaged wiring or poor connections in the steering column, accounting for about 25% of the incidents. Corroded connectors can disrupt the sensor's signals.
- Electrical issues such as a failing body control module (BCM) can also trigger this DTC, resulting in approximately 10% of cases. Regularly scheduled maintenance can prevent this.
- Less common but serious causes include steering column misalignment that affects sensor calibration, which can lead to dangerous driving conditions.
- A rare cause of B0C67 may involve software glitches in the vehicle’s computer system, requiring a software update or reprogramming by a dealership.
