What is C0672?
DTC C0672 refers to an issue with the Steering Angle Sensor, which is critical for stability control and active safety systems in vehicles like the Chevrolet Silverado and GMC Sierra from 2015 to 2018. This code indicates that the sensor is either malfunctioning or providing inaccurate readings. The Steering Angle Sensor helps the vehicle's computer determine the direction of the steering wheel and adjust systems accordingly to maintain control during various driving conditions. When this code is triggered, the vehicle may exhibit erratic steering behavior, difficulty in controlling traction, and potential issues with stability control systems. In real-world driving, you might notice your vehicle handling differently, particularly in slippery conditions, or you may see warning lights on your dashboard, indicating a problem with the vehicle's steering or stability systems. Addressing this issue promptly is crucial for your safety and the longevity of your vehicle's systems.
