What is C064E?
DTC C064E is a diagnostic trouble code indicating an issue with the vehicle's steering angle sensor. This sensor is crucial for stability control systems and helps in determining the position of the steering wheel. When this code appears, it suggests that the steering angle sensor is not functioning correctly or is sending incorrect data to the vehicle's computer system. This can lead to a range of issues, including erratic steering behavior, problems with traction control, and reduced effectiveness of vehicle stability systems. For drivers, this might manifest as an illuminated check engine light or even more severe handling issues during driving. If left unaddressed, the vehicle may experience compromised safety systems, leading to potential accidents. Understanding what this code means is essential for any vehicle owner, especially those who drive models like the Chevrolet Silverado or GMC Sierra, which are often affected by this issue. Regular diagnostics using tools like the GeekOBD APP can help pinpoint the problem before it escalates, ensuring driver safety and vehicle reliability.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C064E is present:
- Check engine light remains illuminated, indicating that the vehicle's computer has detected an issue with the steering system.
- Steering feels loose or unresponsive, causing difficulty in maintaining control during turns or maneuvers.
- Stability control warning light activates, suggesting that the vehicle's traction control system may not function properly.
- Inconsistent steering feedback, where the steering wheel may not return to the center after a turn, leading to potential handling issues.
- Unusual noises from the steering column when turning, which may indicate a mechanical failure in conjunction with the sensor issue.
Possible Causes
Most common causes of C064E (ordered by frequency):
- Faulty steering angle sensor, which is the most common cause and can account for about 60% of C064E cases. This sensor may wear out over time or suffer from internal damage.
- Wiring issues, such as frayed or corroded wires connecting the sensor to the vehicle's computer, leading to incorrect data transmission.
- Improper calibration of the steering angle sensor, often occurring after suspension repairs or alignment adjustments, which can be rectified through a reset procedure.
- Less common but serious causes include a malfunctioning electronic control unit (ECU) that fails to process input from the steering angle sensor, leading to broader vehicle stability issues.
- Rarely, physical obstructions or mechanical failures in the steering system, such as a damaged steering rack, can produce similar symptoms.
