The most common cause of C0FBA is a faulty power steering control module, which can cost around $500 to $800 to replace. Other causes include damaged wiring, which can be repaired for $100 to $300, and issues with the steering angle sensor, which may cost $150 to $250.

Can I drive my car with C0FBA or should I stop immediately?

It is not safe to drive your car with the C0FBA code. The loss of power steering assistance can make steering difficult, especially in tight situations. It's advisable to have your vehicle inspected and repaired as soon as possible.

How can I diagnose C0FBA myself using GeekOBD APP?

To diagnose C0FBA using the GeekOBD APP, first connect the app to your vehicle's OBD2 port. Run a full diagnostics scan to retrieve the code and any related issues. Analyze the freeze frame data to understand the conditions under which the code was triggered, and check for any other codes that may provide additional context.

What vehicles are most commonly affected by C0FBA?

DTC C0FBA is frequently encountered in the 2015-2018 Honda Accord models, but it may also appear in other vehicles equipped with electronic power steering systems, particularly from Honda and Acura.

How can I prevent C0FBA from happening again?

To prevent the C0FBA code from reappearing, ensure regular maintenance of your vehicle's power steering system. Check fluid levels, inspect wiring for wear, and keep the system free of contaminants. Using high-quality parts during repairs can also reduce the chances of future issues.

What is C0FBA?

DTC C0FBA is a diagnostic trouble code that indicates a problem with the vehicle's power steering control module, particularly in models such as the 2015-2018 Honda Accord. This code suggests that the electronic power steering (EPS) system is experiencing a malfunction that can lead to increased steering effort or a complete loss of power steering assistance. In practical terms, when this code is triggered, drivers might notice that their steering feels heavier than usual, especially at lower speeds or during tight turns. In some cases, the power steering warning light on the dashboard may illuminate, indicating a need for immediate attention. The EPS system relies on sensors and motors to provide steering assistance, and any failure in this system can lead to handling difficulties, posing safety risks. Ignoring this code could potentially lead to more severe problems such as complete steering failure, which could endanger the driver and others on the road. Therefore, it is crucial to diagnose and address the issue promptly to ensure safe driving conditions.

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

Symptoms

Common symptoms when C0FBA is present:

  • The power steering warning light illuminates on the dashboard, indicating a malfunction in the EPS system.
  • Steering feels unusually heavy, particularly noticeable during parking or low-speed maneuvers.
  • Unpredictable steering response, where the steering may become unresponsive or overly sensitive at times.
  • Strange noises coming from the steering column when turning the wheel, which may indicate issues with the EPS motor.
  • Inconsistent power steering assistance, leading to a fluctuating steering feel during driving.

Possible Causes

Most common causes of C0FBA (ordered by frequency):

  1. The most common cause of DTC C0FBA is a faulty power steering control module, which occurs in about 60% of cases. This component can fail due to electrical faults or manufacturing defects.
  2. A second potential cause is a damaged wiring harness or poor electrical connections related to the EPS system. Corrosion or frayed wires can lead to signal loss, affecting the module's performance.
  3. Thirdly, low power steering fluid levels or contamination can also trigger this code. Regular maintenance can help prevent fluid-related issues.
  4. In rare cases, a malfunctioning steering angle sensor can lead to this code being set. This sensor is crucial for the EPS system to function correctly.
  5. Lastly, while less common, software glitches in the EPS system can trigger the C0FBA code. Updating the vehicle's software may be necessary in these situations.
