What is C071E?
The Diagnostic Trouble Code (DTC) C071E indicates a fault within the vehicle’s chassis control system, particularly related to the steering angle sensor. This fault can arise from various issues, including wiring problems, sensor malfunction, or software glitches. When this code is triggered, it may affect the vehicle’s handling, stability control, and other related systems, leading to potential safety concerns. In practical terms, if you own a 2015-2018 Chevrolet Silverado or similar models like the GMC Sierra, you might notice the check engine light illuminating. Ignoring this code can lead to more severe issues over time, including compromised steering performance and increased wear on related components. The vehicle's onboard computer uses inputs from the steering angle sensor to determine the vehicle's orientation and control systems like traction control and stability control. If the sensor data is inconsistent or incorrect, it will trigger the C071E code, warning you that immediate attention is needed. Addressing this issue promptly not only ensures a smoother driving experience but also enhances your overall vehicle safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C071E is present:
- The check engine light remains illuminated, signaling a diagnostic issue that needs addressing.
- Drivers may experience unresponsive or erratic steering, making the vehicle difficult to control, especially at higher speeds.
- A noticeable decrease in fuel efficiency could occur, often by 10-15%, due to the vehicle's systems working inefficiently.
- Traction control and stability control systems may disable, risking compromised safety during adverse driving conditions.
- In some cases, drivers might hear unusual noises from the steering column, indicating a potential mechanical failure.
Possible Causes
Most common causes of C071E (ordered by frequency):
- {'cause': 'Faulty steering angle sensor', 'likelihood': '40%', 'details': 'The steering angle sensor can fail due to wear and tear or electrical issues, leading to inaccurate readings.'}
- {'cause': 'Damaged wiring or connectors', 'details': "Wiring issues can cause a break in communication between the sensor and the vehicle's computer, triggering the code."}
- {'cause': 'Software glitch in the vehicle’s control module', 'prevention': 'Regular software updates during maintenance checks can help mitigate this issue.'}
- {'cause': 'Bad ground connection affecting sensor performance', 'details': 'A poor ground connection can result in erratic sensor readings, causing the C071E code to trigger.'}
- {'cause': 'Contamination of the sensor from moisture or debris', 'details': 'Environmental factors can degrade sensor functionality, highlighting the importance of regular vehicle maintenance.'}
