What is C047D?
The diagnostic trouble code (DTC) C047D indicates a problem related to the steering angle sensor circuit in your vehicle. This code typically arises when the vehicle's onboard diagnostics system detects an issue with the sensor that measures the angle of the steering wheel. This measurement is crucial for the vehicle's stability control systems, including electronic stability control (ESC) and traction control. When the C047D code is triggered, it can lead to a variety of symptoms that can affect vehicle handling and safety. Owners of affected vehicles, such as the 2015-2020 Chevrolet Silverado, may notice that the steering feels unresponsive or that the vehicle's traction control system may not function correctly. Ignoring this code could result in decreased vehicle control and increased risk of accidents, especially in slippery conditions. The C047D code typically requires immediate attention. Repairing the issue often involves inspecting the wiring and connectors for damage, replacing the steering angle sensor, or recalibrating the sensor to ensure accurate readings. Regular maintenance and timely repairs can help prevent this issue from becoming more severe.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C047D is present:
- Check engine light illuminates, indicating a malfunction in the steering system.
- Steering feels loose or unresponsive, making it difficult to control the vehicle, especially during turns.
- Traction control warning light may activate, suggesting impaired vehicle stability under acceleration.
- Increased wear on tires due to incorrect alignment caused by sensor errors.
- Odd noises coming from the steering column when turning, indicating potential sensor or mechanical issues.
Possible Causes
Most common causes of C047D (ordered by frequency):
- Faulty steering angle sensor (50% likelihood) - This is the most common cause and can result from wear and tear over time.
- Damaged wiring or connectors (30% likelihood) - Corrosion or physical damage can disrupt the signal transmission from the sensor.
- Improper sensor calibration (10% likelihood) - Following repairs or replacements, the sensor may need recalibration to function correctly.
- Software glitches in the vehicle's ECU (5% likelihood) - Occasionally, the vehicle's software may misinterpret sensor data.
- Less common cause - Physical obstruction or damage to the steering column affecting sensor readings.
