What is C0E31?

The C0E31 diagnostic trouble code (DTC) is an indicator of a fault in the vehicle's electric power steering system. This code typically signifies that the steering assist functionality has been compromised, which can lead to increased steering effort and potential safety concerns while driving. When this code appears, it often points to issues with the steering angle sensor, wiring harness, or the power steering control module itself. The implications of having a C0E31 code present are significant; you may notice your vehicle becoming harder to steer, especially at low speeds, which can affect your ability to maneuver safely. This code is commonly encountered in various makes and models, including the 2013-2017 Ford Focus and the 2014-2018 Chevrolet Malibu. If ignored, it can lead to further mechanical issues and potentially more costly repairs down the line. Therefore, addressing the C0E31 code promptly is crucial for ensuring your vehicle's safety and performance.

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

Symptoms

Common symptoms when C0E31 is present:

  • Check engine light illuminates consistently, indicating a fault that requires immediate attention.
  • Steering feels heavy or unresponsive, especially during low-speed maneuvers or parking.
  • Unusual noises coming from the steering system, such as whining or grinding sounds.
  • Increased effort required to turn the steering wheel, indicating a loss of power assist.
  • Intermittent loss of power steering assist, which can vary based on driving conditions.

Possible Causes

Most common causes of C0E31 (ordered by frequency):

  1. The most common cause of the C0E31 code is a faulty steering angle sensor, which occurs about 60% of the time. This sensor is crucial for proper power steering operation, and if it fails, it can lead to inaccurate input readings.
  2. Another frequent issue is damaged wiring or poor connections in the power steering system, which accounts for around 25% of cases. Corrosion or fraying wiring can interrupt power delivery and signal transmission.
  3. A malfunctioning power steering control module is also a possible cause, representing about 10% of issues. This electronic unit controls the power steering assist and can fail due to internal faults.
  4. Less commonly, low power steering fluid levels can cause the C0E31 code, especially if there are leaks in the system. This is an easily preventable issue through regular maintenance checks.
  5. Lastly, while rare, software glitches in the vehicle's onboard computer systems can trigger the C0E31 code, requiring a software update or reprogramming.
