What is C01C2?
The diagnostic trouble code (DTC) C01C2 indicates an issue with the steering angle sensor, commonly found in vehicles like the 2015-2020 Ford F-150, among others. This sensor plays a crucial role in the vehicle's stability control and anti-lock braking systems. When the C01C2 code is triggered, it typically means that the sensor has detected an abnormal reading or is malfunctioning, which can affect the vehicle's handling and safety. For example, if the steering angle sensor isn't functioning correctly, the vehicle may not track straight or may exhibit erratic behavior while turning. This can lead to increased wear on tires and components, and in severe cases, it can compromise the safety features that help prevent accidents. Owners might notice a warning light on the dashboard, and although the vehicle may still drive, the loss of stability control can be concerning. It's advisable to address this issue promptly to ensure safe driving conditions and proper functionality of vehicle systems. Ignoring this code can lead to more significant problems down the line, including costly repairs and safety hazards.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C01C2 is present:
- The check engine light remains illuminated, indicating a fault with the steering system.
- Unusual steering behavior, such as the vehicle pulling to one side or a delayed response when turning.
- Increased tire wear due to improper alignment as a result of steering angle inaccuracies.
- Activation of the stability control warning light on the dashboard, indicating a potential issue with vehicle stability.
- Difficulty in turning the steering wheel or a feeling of looseness, which may suggest a deeper mechanical issue.
Possible Causes
Most common causes of C01C2 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, which has a likelihood of around 70%. This may stem from wear and tear, exposure to moisture, or electrical issues.
- Another cause can be misalignment of the steering components, which may occur after suspension repairs or accidents, affecting sensor readings.
- Additionally, wiring issues such as frayed wires or bad connectors can lead to incorrect signals being sent to the control module, contributing to the C01C2 code.
- Less commonly, a malfunctioning power steering module can create discrepancies in sensor readings, potentially affecting performance.
- In rare cases, the issue may be linked to the vehicle's software requiring an update or reprogramming to ensure proper communication with the steering system.
