The most common cause of C0B01 is a faulty steering angle sensor, which has a 60% chance of being the issue. Repair costs for replacing the sensor can range from $150 to $300. Other causes include wiring issues and calibration errors, with costs varying depending on the complexity of repairs.

Can I drive my car with C0B01 or should I stop immediately?

While you may still drive your vehicle, it is not recommended. Driving with C0B01 can lead to unpredictable steering behavior and increased accident risk. It's best to schedule repairs as soon as possible to ensure your safety.

How can I diagnose C0B01 myself using GeekOBD APP?

To diagnose C0B01 using the GeekOBD APP, connect the app to your vehicle's OBD2 port. Scan for codes, and check freeze frame data for context on when the code triggered. Review live data to monitor the steering angle sensor's performance during vehicle operation and determine if it's functioning correctly.

What vehicles are most commonly affected by C0B01?

DTC C0B01 is frequently reported in models like the 2016-2021 Ford Explorer and the 2017-2021 Honda CR-V. If you own one of these vehicles, be proactive in monitoring for symptoms to address any issues early.

How can I prevent C0B01 from happening again?

To prevent C0B01 from recurring, ensure regular vehicle maintenance, including electrical system checks. Avoid sudden steering maneuvers that could strain the sensor, and keep the vehicle's software updated to avoid glitches that might trigger false codes.

What is C0B01?

The diagnostic trouble code (DTC) C0B01 indicates a problem with the vehicle's steering sensor. This code is prevalent in newer vehicles, especially in models like the 2016-2021 Ford Explorer and the 2017-2021 Honda CR-V. When this code appears, it typically signals that the steering wheel angle sensor is malfunctioning or out of calibration. The steering sensor is crucial for stability control systems and advanced driver-assistance features, which means that a failure can lead to poor handling, unexpected loss of control, or failure of systems such as lane-keeping assistance. These issues can increase the risk of accidents, making it essential to address this code promptly. Common indicators include the illumination of the check engine light, steering feedback anomalies, or difficulty in steering. If left unresolved, it may lead to further complications, impacting driving safety and vehicle functionality.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0B01 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the steering sensor.
  • Steering feels loose or unresponsive, making it difficult to control the vehicle, especially at higher speeds.
  • Unusual noises when turning the steering wheel, such as grinding or clicking sounds that signify underlying mechanical issues.
  • Inconsistent steering feedback, where the steering wheel may feel heavier or lighter than usual during turns.
  • Warning messages on the dashboard related to stability control or driver assistance features, suggesting a malfunction.

Possible Causes

Most common causes of C0B01 (ordered by frequency):

  1. Faulty steering angle sensor (60% likelihood) - The most common cause, where the sensor fails due to wear and tear or electrical issues.
  2. Wiring issues (20% likelihood) - Damaged or frayed wires can disrupt the signal between the steering sensor and the vehicle's control module.
  3. Calibration errors (15% likelihood) - The steering angle sensor may require recalibration after repairs or battery disconnections.
  4. Less common but serious cause: Steering rack failure - A mechanical failure in the steering rack can also trigger this code, requiring significant repairs.
  5. Rare but possible cause: Software glitches - Occasionally, outdated software in the vehicle's ECU can lead to false readings and trigger DTC C0B01.
