What is C0587?

The diagnostic trouble code (DTC) C0587 indicates a problem with the steering angle sensor in vehicles like the 2010-2015 Chevrolet Equinox and GMC Terrain. This sensor is crucial for the vehicle's stability control systems, as it helps the onboard computers understand the direction in which the steering wheel is turned. When the system detects a malfunction in the sensor, it triggers the C0587 code. Drivers may experience issues such as the stability control light illuminating on the dashboard or difficulty with traction control systems. Real-world implications can include compromised vehicle handling, especially in adverse road conditions, and increased risk of losing control of the vehicle. If not addressed, this issue can lead to faulty performance of the electronic stability control (ESC) and anti-lock braking system (ABS), which are critical for safe driving. Proper diagnostics using tools like the GeekOBD APP can help pinpoint the specific issues related to the steering angle sensor and guide necessary repairs.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0587 is present:

  • The stability control light remains illuminated on the dashboard, indicating a system fault.
  • Drivers may notice unusual steering behavior, such as delayed response or stiffness when turning the steering wheel.
  • Fuel economy might decrease, potentially by 10-15%, as the vehicle compensates for stability issues.
  • The vehicle may occasionally lose traction during acceleration, particularly on slippery surfaces.
  • The anti-lock braking system (ABS) may not engage properly, leading to longer stopping distances.

Possible Causes

Most common causes of C0587 (ordered by frequency):

  1. The most common cause of DTC C0587 is a faulty steering angle sensor, with an occurrence likelihood of around 60%. This sensor can fail due to wear and tear or electrical malfunctions.
  2. Another possible cause is damaged wiring or connectors associated with the steering angle sensor. This could result in intermittent signals being sent to the vehicle's ECU.
  3. Improper alignment or issues with the steering column can also lead to this code being triggered. Regular maintenance and alignment checks can prevent such issues.
  4. Less commonly, software glitches or ECU failures can cause erroneous readings from the steering angle sensor, although this is rare.
  5. In some instances, aftermarket modifications to the vehicle's steering system may interfere with the sensor's operation, resulting in the C0587 code.
