What is C0BB7?
DTC C0BB7 is a diagnostic trouble code indicating a problem with the steering angle sensor, particularly in vehicles equipped with electronic power steering systems. This code usually arises when the sensor's input signal is deemed abnormal by the vehicle's onboard diagnostic system. The steering angle sensor plays a crucial role in ensuring that the vehicle's stability control systems operate effectively. When this sensor malfunctions, drivers might experience issues such as erratic steering response, difficulty in steering, or the activation of other warning lights on the dashboard. On a 2017-2021 Ford F-150, for instance, this might manifest as an unresponsive steering wheel or the vehicle's electronic stability control system failing to engage properly. Ignoring this code can lead to compromised vehicle handling and safety, making it imperative to address the issue promptly. If you're experiencing symptoms associated with this DTC, it’s advisable to seek professional diagnosis and repair to ensure safe vehicle operation.
