Using the GeekOBD APP, you can scan your vehicle for trouble codes, view freeze frame data, and monitor live data to pinpoint the issue in the EPS system.
What vehicles are most commonly affected by C06BB?
The C06BB code is frequently reported in 2015-2020 Ford F-150 models, but it can appear in other Ford vehicles equipped with EPS systems.
How can I prevent C06BB from happening again?
Regular maintenance, including checking wiring connections and ensuring the EPS system is functioning correctly, can help prevent C06BB from recurring.
What is C06BB?
DTC C06BB is a diagnostic trouble code that indicates an issue related to the vehicle's power steering system, specifically concerning the electric power steering (EPS) control module. This code is most commonly seen in vehicles like the 2015-2020 Ford F-150. When this code is triggered, it typically means there is a fault within the EPS system, which can lead to various driving issues. The EPS system is crucial for ensuring that steering is smooth and responsive. If the system malfunctions, you may notice that your steering feels heavier or less responsive than usual. In some cases, drivers might also experience sudden loss of steering assist, which can pose serious safety risks. It's important to address this issue quickly, as continued driving with a C06BB code can lead to further damage to the steering system or associated components. The C06BB code can also illuminate the check engine light, alerting you to the need for immediate diagnostics. To resolve the issue, a thorough inspection of the EPS system, including wiring and connectors, will be necessary, alongside possible reprogramming of the EPS control module.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C06BB is present:
- Check engine light illuminates, typically remaining on until the issue is resolved.
- Steering feels unusually heavy, especially during low-speed maneuvers or when turning.
- Sudden loss of power steering assist, making it difficult to steer the vehicle.
- Unusual noises such as whining or grinding from the steering column area.
- Potential fluctuations in the steering response, leading to inconsistent handling.
Possible Causes
Most common causes of C06BB (ordered by frequency):
- {'cause': 'Faulty EPS control module (30% likelihood)', 'details': 'A malfunctioning control module can disrupt steering assist, leading to the C06BB code.'}
- {'cause': 'Damaged wiring or connectors (25% likelihood)', 'details': 'Corroded or broken wires can interrupt communication between the EPS system components.'}
- {'cause': 'Low power steering fluid levels (15% likelihood)', 'details': 'Although EPS systems are generally sealed, leaks can occasionally occur, affecting performance.'}
- {'cause': 'Failed steering angle sensor (20% likelihood)', 'details': "This sensor helps the EPS system determine the driver's steering input, and failure can trigger C06BB."}
- {'cause': 'Software issues or glitches (10% likelihood)', 'details': 'In some cases, programming errors can cause the EPS system to behave erratically.'}
