What is C0468?

The DTC C0468 code indicates a problem with the steering angle sensor, which is crucial for the stability control and traction control systems in vehicles. This code is commonly found in various Chevrolet, GMC, and Cadillac models from around 2010 to 2020. The steering angle sensor measures the angle of the steering wheel and communicates this information to the vehicle's electronic control unit (ECU). A malfunctioning sensor can lead to compromised handling and stability, increasing the risk of accidents. Real-world implications include issues with traction control and electronic stability systems, which are designed to keep your vehicle stable during turns and slippery conditions. If left unaddressed, you may experience erratic vehicle behavior, such as unexpected steering responses or difficulty in controlling your vehicle, especially during sharp turns or in adverse weather conditions. Furthermore, the check engine light may illuminate, prompting you to seek diagnostic assistance. Understanding the significance of the C0468 code is vital for ensuring your vehicle’s safety and maintaining optimal performance.
