What is C07B3?

DTC C07B3 is a diagnostic trouble code that indicates a fault within the vehicle's steering assist system, specifically related to the steering column or the electric power steering (EPS) system. When this code is triggered, your vehicle's onboard computer recognizes that there is an issue affecting the steering functionality, which may lead to a lack of assistance when steering, making the vehicle harder to control. Commonly found in vehicles like the 2015-2018 Ford F-150, C07B3 can result from a variety of underlying issues, such as a faulty steering angle sensor, damaged wiring, or a malfunctioning EPS motor. If left unaddressed, this code can compromise your vehicle's safety, as it may lead to steering failure or inconsistent steering response. Drivers may experience various symptoms, including a warning light on the dashboard, difficulty steering, or even a complete loss of power steering. Thus, understanding and diagnosing this code promptly is crucial for safe vehicle operation.

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

Symptoms

Common symptoms when C07B3 is present:

  • The check engine light illuminates or flashes frequently, indicating a serious issue.
  • Steering feels heavy or unresponsive, especially at low speeds, making it difficult to maneuver.
  • A noticeable decrease in fuel efficiency, potentially causing a drop of 10-15%, due to the steering system working harder.
  • Unusual noises such as grinding or clicking coming from the steering column when turning the wheel.
  • The steering wheel may vibrate or feel loose, leading to an unsettling driving experience.

Possible Causes

Most common causes of C07B3 (ordered by frequency):

  1. The most common cause of DTC C07B3 is a faulty steering angle sensor, which can occur in about 45% of cases. This sensor helps the vehicle understand the driver's steering inputs, and when it fails, it can confuse the EPS system.
  2. Another frequent cause is damaged wiring or poor connections within the steering column, accounting for around 30% of occurrences. Corrosion can lead to intermittent faults, which may trigger the code.
  3. A malfunctioning EPS motor, which provides the necessary assistance for steering, can also trigger this code. Regular maintenance checks can help prevent such failures.
  4. Less common but serious, a complete failure of the steering control module can occur, which may require extensive diagnosis and replacement.
  5. In rare cases, software glitches in the vehicle's ECU (Engine Control Unit) can lead to false triggering of the C07B3 code, necessitating a software update.
