What is C01C8?
DTC C01C8 refers to a diagnostic trouble code that indicates a loss of communication with the steering angle sensor. This sensor is crucial for systems like Electronic Stability Control (ESC) and Advanced Driver Assistance Systems (ADAS). When the vehicle's onboard diagnostic system detects that the steering angle sensor is not transmitting data effectively, it triggers this code. The steering angle sensor monitors the position of the steering wheel and sends this data to the vehicle's ECU to help control stability, traction, and assistive steering functions. If this code appears, drivers may experience issues such as the traction control warning light illuminating on the dashboard, difficulty with steering response, or even complete failure of electronic stability systems. Ignoring this code can lead to more significant safety concerns, especially in adverse driving conditions. In vehicles like the 2015-2019 Ford F-150, C01C8 is a common issue that can stem from wiring problems, sensor failure, or issues within the vehicle's electrical system. Recognizing and addressing this code promptly is essential for maintaining vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C01C8 is present:
- The traction control light illuminates on the dashboard, indicating a malfunction within the stability control system.
- Steering feels unresponsive or heavier than usual, making it difficult to control the vehicle in certain conditions.
- Inconsistent or delayed response from the steering system, particularly when making sharp turns or during sudden maneuvers.
- Check engine light may also be present, indicating multiple issues that need further inspection.
- Unusual noises from the steering column could occur, signaling potential mechanical or electrical problems.
Possible Causes
Most common causes of C01C8 (ordered by frequency):
- The most common cause of C01C8 (approximately 60%) is a faulty steering angle sensor, which may fail due to wear or electrical issues.
- Another frequent cause (about 25%) is damaged wiring or connectors between the steering angle sensor and the ECU, often due to wear and tear or exposure.
- An improperly calibrated steering angle sensor can also trigger this code, especially after repairs or replacements, making proper calibration essential.
- Less common but serious causes include issues with the vehicle's ECU itself, such as software glitches or internal failures.
- A rare cause (under 5%) could involve problems with the power steering pump, which may affect sensor readings and overall steering performance.
