What is C0472?

The C0472 diagnostic trouble code indicates an issue with the steering angle sensor, which is crucial for stability control and traction control systems. This code is common in vehicles like the 2015-2018 Chevrolet Silverado, where the steering angle sensor's readings are either out of range or not aligned correctly. Essentially, the steering angle sensor monitors the position of the steering wheel and sends this data to the vehicle's computer. When the computer detects that the sensor data doesn't match expected parameters, it triggers the C0472 code. Ignoring this code can lead to compromised vehicle handling, especially in slippery conditions, as the stability control system may not function properly. Additionally, the check engine light may illuminate, warning drivers of the underlying issue. It is essential for vehicle safety and performance to address the C0472 code promptly, ensuring that the steering angle sensor is functioning correctly and that the vehicle's safety systems are operational.
