What is C08E9?

The DTC C08E9 code is an indication of a fault within a vehicle's electrical system, specifically related to the power steering control module (PSCM) or the steering assist system. When this trouble code appears, it typically signifies that the vehicle’s power steering system is experiencing issues, which can lead to a significant decrease in steering assist. This can make steering feel heavy or unresponsive, which can be especially dangerous in tight driving situations and parking. The C08E9 code is often triggered by either a malfunctioning PSCM or issues with the wiring harness connected to it, including corrosion or shorts. If left unaddressed, this issue can impact overall vehicle safety, as power steering is critical for steering control, particularly at lower speeds. Owners of affected vehicles, such as 2015-2020 Ford Explorers, should be vigilant about this code and seek diagnostics promptly to avoid potential steering failures or accidents. Fixing this issue usually involves inspecting the wiring, replacing the PSCM, or ensuring proper communication between the components.

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

Symptoms

Common symptoms when C08E9 is present:

  • The check engine light is illuminated, often accompanied by a warning message on the dashboard regarding power steering assist.
  • Drivers may notice that the steering feels unusually heavy, especially at lower speeds, making maneuvering the vehicle difficult.
  • Fuel economy may decrease as the engine works harder to compensate for the steering system's inefficiencies, potentially leading to a drop of 10-15%.
  • In some cases, drivers may hear unusual noises from the steering column or pump, indicating potential failure.
  • The vehicle may exhibit intermittent steering assist loss, where the system works sometimes but fails at other times, increasing driving risk.

Possible Causes

Most common causes of C08E9 (ordered by frequency):

  1. {'cause': 'Malfunctioning Power Steering Control Module (PSCM)', 'likelihood': '60%', 'details': 'The PSCM is responsible for regulating power steering assist; a failure here is the most common cause of the C08E9 code.'}
  2. {'cause': 'Corroded or Damaged Wiring', 'technicalExplanation': 'Wiring issues such as corrosion or loose connections can disrupt communication to the PSCM, leading to faults.'}
  3. {'cause': 'Faulty Steering Angle Sensor', 'preventionTips': 'Regular maintenance and inspections can help identify issues with sensors, preventing future problems.'}
  4. {'cause': 'Software Glitches in the PSCM', 'details': 'Updates or resets may be needed to resolve communication errors between control modules.'}
  5. {'cause': 'Low Power Steering Fluid', 'details': 'While less common, low fluid levels can cause steering issues; always check fluid levels as part of regular maintenance.'}
