How can I prevent C087C from happening again?
Regular maintenance, including inspections of the steering system and timely replacement of worn components, can help prevent the recurrence of C087C.
What is C087C?
The diagnostic trouble code C087C typically indicates a problem with the steering angle sensor circuit in vehicles equipped with advanced driver-assistance systems (ADAS). This code is often found in popular models such as the Chevrolet Silverado (2014-2019) and GMC Sierra (2014-2019). When your vehicle's onboard diagnostics detect an inconsistency with the steering angle sensor, it triggers the C087C code. This sensor is crucial for systems like electronic stability control (ESC) and traction control, which help maintain vehicle stability during maneuvers. A malfunction can lead to these systems not functioning correctly, putting you at risk, especially in slippery conditions. Drivers may notice the check engine light illuminating, and if the problem persists, it can lead to further issues such as erratic handling or increased tire wear. Ignoring this code can compromise your safety and the vehicle's performance, making it essential to address it promptly. Understanding C087C means acknowledging the importance of the steering angle sensor in maintaining your vehicle’s stability and safety systems.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C087C is present:
- The check engine light remains illuminated, indicating a fault in the vehicle’s system.
- You may experience delayed steering response, making the vehicle feel unresponsive during turns.
- Drivers might notice increased tire wear due to improper alignment caused by a faulty steering angle sensor.
- The vehicle may exhibit erratic behavior when cornering, such as unexpected drifting or stability control warnings.
- In some cases, you might hear unusual noises from the steering column, indicating potential sensor issues.
Possible Causes
Most common causes of C087C (ordered by frequency):
- The most common cause of C087C is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor can wear out over time due to continuous use.
- Another frequent issue is wiring problems, such as damaged wires or loose connections in the steering angle sensor circuit, accounting for around 25% of cases.
- Improper calibration after replacing steering components can also trigger this code. Regular maintenance and checks are essential.
- Less commonly, a malfunctioning electronic control unit (ECU) can misinterpret sensor data, leading to a C087C code.
- In rare instances, a steering column issue, like a stuck or malfunctioning gear, may also trigger this code.
