What is C0487?

DTC C0487 is a diagnostic trouble code that indicates a problem with the steering angle sensor circuit. This sensor is crucial for the proper functioning of the vehicle's stability control and traction control systems, which help keep your car stable during turns and adverse conditions. When the C0487 code is triggered, it usually means that the steering angle sensor is experiencing issues such as incorrect calibration, wiring problems, or a malfunctioning sensor itself. This can lead to symptoms such as the vehicle's stability control system not working correctly, which can be particularly dangerous in slippery conditions. In real-world terms, if you notice your car's handling feels off or the stability control light is illuminated on your dashboard, it’s essential to address this code promptly. Ignoring it could lead to compromised vehicle safety and increased wear on other components. Depending on your vehicle make and model, like the 2015 Honda Accord or the 2016 Ford Fusion, the symptoms and severity might vary, but the underlying issues usually involve the steering system's integrity.

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

Symptoms

Common symptoms when C0487 is present:

  • The 'Check Engine' light is illuminated, indicating a problem with the steering angle sensor.
  • Stability control warning light remains on, suggesting that the system may not function properly during maneuvers.
  • Vehicle may feel unstable during turns, leading to increased driver anxiety and difficulty controlling the car.
  • Increased steering effort may be required, indicating a potential issue with the steering assist system.
  • Unusual noises when turning the steering wheel, which could indicate wear in the steering components.

Possible Causes

Most common causes of C0487 (ordered by frequency):

  1. Faulty steering angle sensor - This is the most common cause, accounting for about 65% of the cases. The sensor may fail due to wear or manufacturing defects.
  2. Wiring issues - Damaged or corroded wiring can cause interruptions in the sensor signal, contributing to a 20% likelihood of triggering the code.
  3. Improper calibration - If the steering angle sensor is not calibrated correctly after a repair or replacement, it may trigger the C0487 code, seen in about 10% of cases.
  4. Steering rack issues - While less common, problems with the steering rack can cause incorrect sensor readings, resulting in a 5% chance of being the culprit.
  5. Software issues - Rarely, a software glitch in the vehicle’s control module may falsely trigger the code, with a likelihood of about 2%.
