What is C065B?

The diagnostic trouble code (DTC) C065B indicates a malfunction related to the vehicle's steering angle sensor. This sensor plays a crucial role in determining the position of the steering wheel, which is essential for systems like traction control, stability control, and advanced driver-assistance systems (ADAS). When the C065B code is triggered, it typically means that the sensor is sending incorrect signals to the vehicle's onboard computer or that there is an issue with the communication between the sensor and the vehicle's control modules. This can lead to various performance issues, such as poor handling, unexpected steering behavior, or the illumination of warning lights on the dashboard. If your vehicle is a 2016-2021 Chevrolet Malibu, or similar models from GM, it's particularly important to address this issue promptly, as it can affect your vehicle's safety and drivability. Ignoring the C065B code can lead to a cascading failure of related systems, resulting in higher repair costs and potential safety hazards. Regular maintenance and timely diagnostics using tools like the GeekOBD APP can help identify the root cause and prevent serious problems down the line.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C065B is present:

Check engine light remains illuminated, indicating that there's a persistent issue with the vehicle's steering system.
Steering feels loose or unresponsive, which can create difficulty in controlling the vehicle, especially during turns.
Traction control or stability control warning lights may activate, indicating that these systems are disabled due to the steering sensor error.
Vehicle may exhibit unexpected behaviors, such as oversteering or understeering, making it unsafe to drive in certain conditions.
Reduced fuel efficiency might occur due to the vehicle's systems working harder to compensate for the sensor malfunction.

Possible Causes

Most common causes of C065B (ordered by frequency):

The most common cause of C065B is a faulty steering angle sensor, occurring in about 60% of cases. This sensor can wear out or become damaged over time, especially in vehicles frequently driven on rough terrain.
Another common cause is poor electrical connections, which can account for around 25% of issues. Corrosion or loose wires can disrupt communication between the sensor and the vehicle's computer.
Software glitches in the vehicle's control modules can also cause this code, occurring in about 10% of cases. Regular updates from the dealership may help prevent these issues.
Less commonly, a malfunctioning steering rack can trigger C065B, especially if the rack is experiencing physical damage.
In rare cases, a complete failure of the vehicle's electronic control unit (ECU) can lead to this error, though this is typically accompanied by other significant symptoms.
