What is C0559?
DTC C0559 indicates a calibration error with the steering angle sensor, a crucial component for systems like electronic stability control (ESC) and anti-lock braking systems (ABS). When this code is triggered, it suggests that the vehicle's steering angle sensor is either out of calibration or has malfunctioned. This is particularly common in vehicles such as the 2010-2015 Chevrolet Equinox and the 2014-2018 GMC Terrain. The steering angle sensor provides data to the vehicle’s control modules about the position of the steering wheel. If the system cannot correctly determine this angle, it can lead to issues with the vehicle's handling and stability. Drivers might notice symptoms like the check engine light illuminating, or in some cases, the vehicle may have difficulty with stability control features, possibly resulting in a less safe driving experience. It's important to address this error promptly to ensure vehicle safety and reliability. Ignoring the problem could lead to further complications and higher repair costs down the line.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0559 is present:
- The check engine light stays on constantly, indicating a persistent issue.
- Drivers may experience a feeling of instability while driving, especially during turns.
- The ESC warning light may illuminate, suggesting that the stability control system is disabled.
- Steering feels unresponsive or overly sensitive, impacting vehicle handling.
- The vehicle may pull to one side when driving straight, indicating alignment issues.
Possible Causes
Most common causes of C0559 (ordered by frequency):
- The most common cause of C0559 is a faulty steering angle sensor, with a likelihood of 60%. This can happen due to wear or damage from road conditions.
- Another cause could be improper installation of the steering angle sensor, especially after steering column repairs, which can lead to misalignment.
- A third potential cause is a malfunctioning or dirty connector, which can interrupt the signal from the sensor to the control module. Regular inspections can help prevent this.
- Less common, but serious, could be an issue with the vehicle’s ABS control module, affecting multiple systems.
- Rarely, electrical issues such as short circuits can also trigger this code, often requiring extensive diagnostic work to identify.
