Regular maintenance, including checking the power steering system for wear and tear and ensuring proper fluid levels, can help prevent C09FE from recurring. Also, promptly addressing any steering issues can avoid future problems.

What is C09FE?

The diagnostic trouble code (DTC) C09FE generally indicates an issue with the vehicle's powertrain control module (PCM) and its communication with other modules within the vehicle. Specifically, C09FE is related to a fault in the electric power steering system, which may lead to difficulties in steering or an unresponsive steering wheel. This code is often seen in vehicles like the 2016-2020 Ford Explorer, where drivers may experience a sudden loss of power steering assist, making it challenging to maneuver the vehicle. In the real world, this can be alarming, especially if it occurs while driving in traffic or on a highway. Ignoring this code could lead to further damage to the steering system, resulting in more costly repairs and potentially compromising vehicle safety. If you see this code, it’s crucial to address it promptly to ensure safe operation and maintain vehicle performance. A qualified technician can perform diagnostics to pinpoint the exact issue and recommend necessary repairs or part replacements.

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

Symptoms

Common symptoms when C09FE is present:

  • The 'Check Engine' light might illuminate alongside other warning indicators related to steering.
  • Drivers report the steering feels heavier, particularly at low speeds or when maneuvering in tight spaces.
  • Fuel efficiency may decrease by up to 15% due to the increased effort required to steer the vehicle.
  • Unusual noises such as whining or grinding when steering may be present, indicating a potential failure in the power steering pump.
  • In some cases, a complete loss of power steering assist can occur unexpectedly, making the vehicle difficult to control.

Possible Causes

Most common causes of C09FE (ordered by frequency):

  1. The most common cause of C09FE is a failure in the electric power steering control module, which occurs in about 60% of the cases. This module regulates the amount of assist provided to the steering system.
  2. Another common cause is wiring issues or poor connections in the power steering system, which can lead to intermittent failures. This accounts for around 25% of C09FE occurrences.
  3. A malfunctioning steering angle sensor can also trigger this code, as it provides critical input to the PCM regarding steering position. Regular inspections can help prevent this issue.
  4. Less common, but serious, a failure of the power steering pump itself can lead to C09FE, resulting in complete loss of steering assistance, which is especially dangerous.
  5. In rare cases, software glitches in the PCM may cause false triggers of C09FE, requiring a software update or reprogramming to resolve.
