What is C0662?
DTC C0662 refers to a diagnostic trouble code indicating an issue with the steering angle sensor circuit. This code is commonly found in vehicles like the 2015-2018 Chevrolet Silverado and GMC Sierra. The steering angle sensor is a crucial component for stability control systems as it helps in determining the direction the driver intends to steer. When this sensor malfunctions, it can lead to erratic vehicle handling, especially during turns or emergency maneuvers. In real-world situations, you might notice an illuminated check engine light, or your vehicle may feel less stable while driving. Ignoring this code can lead to further complications, such as reduced traction control effectiveness, which can compromise safety. Therefore, understanding and addressing DTC C0662 promptly is essential for ensuring your vehicle's safety and performance. If you're experiencing issues related to this code, it's advisable to seek a professional mechanic's help to avoid any potential accidents or further damage to the vehicle system.
