What is C06EA?

The DTC C06EA code indicates a problem with the power steering assist system in your vehicle. This code is particularly common among vehicles equipped with electronic power steering systems, which are designed to enhance steering feel and reduce driver effort. When your vehicle's computer detects a malfunction in this system, it triggers the C06EA code, often accompanied by the illumination of the check engine light. The implications of this code are significant. If left unaddressed, it can lead to steering difficulties, making it hard to maneuver your vehicle safely. Drivers may experience heavy steering, especially at low speeds, or even a complete loss of power steering assist in severe cases. Common vehicles affected by this code include the 2016-2019 Chevrolet Malibu and 2017-2020 GMC Acadia, among others. The presence of this code generally suggests an underlying issue with the power steering control module, wiring, or the steering angle sensor. Addressing the C06EA code promptly is crucial to ensure your vehicle’s steering system functions correctly, thus maintaining both safety and drivability.

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

Symptoms

Common symptoms when C06EA is present:

  • The check engine light remains illuminated, indicating a problem that needs attention.
  • Drivers may notice heavy steering, especially when parking or making tight turns, leading to discomfort and difficulty.
  • Fuel economy may decrease by 10-15% due to the increased effort required to steer the vehicle.
  • Unusual noises from the steering column, such as grinding or whining, may be audible when turning the steering wheel.
  • The steering wheel may feel unresponsive or jittery, making it hard to maintain control of the vehicle.

Possible Causes

Most common causes of C06EA (ordered by frequency):

  1. {'cause': "Faulty power steering control module (60%) - This is the most common issue, where the control module fails to communicate properly with the vehicle's ECU.", 'details': "When this module malfunctions, it can disrupt the power steering assist system's functionality, leading to the C06EA code."}
  2. {'cause': 'Wiring issues (25%) - Damaged wiring or loose connections in the power steering system can interrupt the signal between the control module and the steering system.', 'details': 'Corrosion or frayed wires can lead to intermittent failures or complete loss of assist.'}
  3. {'cause': 'Faulty steering angle sensor (10%) - A malfunctioning steering angle sensor can send incorrect data to the power steering control module, resulting in improper operation.', 'prevention': 'Regular inspections can help catch sensor issues early.'}
  4. {'cause': 'Hydraulic fluid leaks (3%) - In hydraulic power steering systems, leaks can cause loss of assist, though this is less common with electronic systems.', 'details': 'Check for fluid levels regularly to prevent issues.'}
  5. {'cause': 'Rare electronic component failure (2%) - In rare cases, other electronic components tied to the power steering system may fail, leading to this code.', 'details': 'Consult a professional if other causes are ruled out.'}
