What is C07B6?
DTC C07B6 is a diagnostic trouble code that indicates a malfunction in the vehicle's powertrain control module (PCM) related to the steering angle sensor. This code is particularly common in 2015-2019 Chevrolet Silverado models. When the C07B6 code is triggered, it typically means that the PCM has detected an issue with the communication from the steering angle sensor, which is crucial for the vehicle's stability control and steering assistance systems. In simpler terms, this means that your vehicle may experience issues with handling and steering response, which can be dangerous. The steering angle sensor monitors the position of the steering wheel and sends this information to the PCM. If the PCM receives faulty or no data, it triggers the C07B6 code and may cause the 'Check Engine' or 'Service Stabilitrak' light to illuminate on the dashboard. Ignoring this code could lead to impaired steering and handling characteristics, making your vehicle less safe to drive. It's important to address this code promptly to maintain vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C07B6 is present:
- The 'Check Engine' light remains illuminated, indicating a potential fault in the vehicle's systems.
- Drivers may notice that the steering feels loose or unresponsive, especially during turns or maneuvers.
- There may be a noticeable decrease in vehicle stability, particularly when navigating corners or during sudden stops.
- In some cases, the 'Service Stabilitrak' warning may appear, alerting drivers to potential issues with the vehicle's traction control.
- Unusual noises from the steering column during turns could also signify a malfunction in the steering angle sensor.
Possible Causes
Most common causes of C07B6 (ordered by frequency):
- The most common cause of the C07B6 code is a faulty steering angle sensor, accounting for approximately 60% of cases. This sensor can wear out over time or become misaligned, leading to incorrect data being sent to the PCM.
- Another possible cause is damaged wiring or connectors related to the steering angle sensor. Corrosion or frayed wires can disrupt communication, making this the second most likely cause, seen in about 25% of instances.
- A third cause could be a software issue within the PCM. Sometimes, a simple software update can resolve the communication errors, which is often overlooked during diagnostics.
- Less commonly, the problem might stem from a malfunction in the stability control module, which could require specialized diagnostic tools to identify.
- In rare cases, the issue could originate from a complete failure of the PCM itself, which would necessitate a costly replacement.
