What vehicles are most commonly affected by C0574?

C0574 is frequently reported in Chevrolet and GMC vehicles, particularly models from 2015-2020. Vehicles like the Chevrolet Silverado, GMC Sierra, and various Cadillac models often experience this code due to the steering angle sensor's location and exposure.

How can I prevent C0574 from happening again?

To prevent the C0574 code from recurring, regularly inspect the steering system and keep the wiring clean and free from moisture. Also, ensure that all electrical connections are secure. Scheduling routine maintenance checks can help catch potential issues before they escalate.

What is C0574?

The DTC C0574 code indicates an issue with the steering angle sensor in vehicles, particularly common in Chevrolet and GMC models. This diagnostic trouble code (DTC) typically arises when the vehicle's onboard computer detects that the steering angle sensor is providing readings that are outside the specified parameters. The steering angle sensor is crucial for various systems, including stability control and traction control, as it helps the vehicle's computer understand the direction the driver intends to go. When this sensor malfunctions, you may notice issues like reduced steering responsiveness or malfunctioning electronic stability control. Ignoring this code can lead to more severe handling problems, which may compromise safety. For instance, drivers may experience difficulty steering or may find that their vehicle doesn't respond as expected during maneuvers, particularly in slippery conditions. Regular diagnostics and timely repairs are essential to maintain vehicle performance and safety. If you encounter this code, it’s advisable to have it addressed promptly to avoid further complications down the road.

Symptoms

Common symptoms when C0574 is present:

  • The check engine light remains illuminated, indicating a persistent issue with the steering system.
  • Steering feels unresponsive or vague, making it difficult to control the vehicle accurately during turns.
  • Electronic stability control activates unexpectedly, which could lead to safety concerns in adverse driving conditions.
  • The vehicle may experience erratic behavior when trying to correct its path, especially during acceleration or cornering.
  • Inconsistent steering response; the steering wheel may feel loose or require more effort to maneuver.

Possible Causes

Most common causes of C0574 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which occurs in around 60% of cases. This may result from wear and tear or exposure to moisture.
  2. A second possibility is damaged wiring or connectors leading to the sensor, which can disrupt the signal sent to the vehicle's computer.
  3. Another cause could be software issues with the vehicle's control module; sometimes a simple update can resolve the problem.
  4. Less common but serious is a failing power steering system, which can lead to difficulties in steering and requires immediate attention.
  5. A rare cause is a misalignment of the steering column, which can affect sensor readings and may need professional adjustments.
