Common Questions

What does B06FE mean and how does it affect my car?

DTC B06FE indicates a malfunction in the electric power steering system. This can lead to heavy steering, especially at low speeds, and may compromise vehicle safety. It's essential to address this issue quickly to avoid further complications.

What are the most common causes of B06FE and how much does it cost to fix?

The most common causes of B06FE include a faulty power steering control module, wiring issues, and low fluid levels. Repair costs can range from $100 for simple wiring repairs to $600 for module replacement.

Can I drive my car with B06FE or should I stop immediately?

While you can technically drive your vehicle with a B06FE code, it's not advisable due to the risk of losing power steering assistance. It's best to stop and address the issue to ensure safe driving conditions.

How can I diagnose B06FE myself using GeekOBD APP?

With the GeekOBD APP, you can perform a scan of your vehicle to retrieve the B06FE code and view freeze frame data. This will help you understand the conditions under which the fault occurred, leading to a more informed diagnosis.

What vehicles are most commonly affected by B06FE?

DTC B06FE is frequently seen in the 2015-2018 Chevrolet Silverado. Other GM models with similar systems may also exhibit this code, particularly if they experience steering issues.

How can I prevent B06FE from happening again?

Regular vehicle maintenance, including wiring inspections and software updates, can help prevent B06FE. Additionally, keeping an eye on power steering fluid levels will ensure the system functions optimally.

What is B06FE?

DTC B06FE is a diagnostic trouble code that indicates a fault in the vehicle's power steering assist system, specifically related to the electric power steering control module. This code often appears in models like the 2015-2018 Chevrolet Silverado, where the electric steering assist may fail. When this code is triggered, the vehicle may lose power steering assistance, making it difficult to steer, especially at low speeds. The system is designed to enhance steering performance and reduce driver effort, but a malfunction can lead to increased steering effort and potentially dangerous driving conditions. Beyond the immediate steering difficulties, ignoring a B06FE code can lead to further electrical and mechanical issues. It's crucial to address this warning promptly, as prolonged driving with this code can exacerbate the problem and lead to expensive repairs down the line.

Symptoms

Common symptoms when B06FE is present:

The check engine light remains illuminated, signaling a system error.
Steering becomes stiff and unresponsive, especially when turning at low speeds, making driving more challenging.
Increased effort is required to turn the steering wheel, particularly noticeable during parking or tight maneuvers.
A temporary loss of power steering assist may occur, resulting in sudden changes in steering feel.
Unusual noises from the steering column while turning, indicating a potential mechanical issue.

Possible Causes

Most common causes of B06FE (ordered by frequency):

{'cause': 'Faulty power steering control module', 'likelihood': '40%', 'details': 'The control module manages the electric power steering system, and a malfunction can directly trigger the B06FE code.'}
{'cause': 'Wiring issues or poor connections', 'details': 'Damaged or corroded wiring can disrupt the signals between the control module and the power steering system, leading to failures.', 'likelihood': '30%'}
{'cause': 'Low power steering fluid levels', 'details': 'While primarily associated with hydraulic systems, low fluid levels can also affect electric systems in some cases. Regular checks can prevent this issue.', 'likelihood': '15%'}
{'cause': 'Malfunctioning electric motor', 'details': 'The electric motor that assists in steering may fail, requiring replacement. This is less common but can be costly to repair.', 'likelihood': '10%'}
{'cause': 'Software glitches in the control module', 'details': 'Occasionally, software updates or resets are necessary to resolve communication issues within the system.', 'likelihood': '5%'}
