What vehicles are most commonly affected by C0F65?

The C0F65 code is commonly reported in models like the 2015-2018 Honda Accord and similar vehicles from other manufacturers that utilize electronic steering systems. Always check for any recalls or technical service bulletins (TSBs) related to these models.

How can I prevent C0F65 from happening again?

To prevent the C0F65 code from recurring, regularly inspect the vehicle's steering and suspension systems, and ensure that software updates are applied as recommended by the manufacturer. Keeping the steering components clean and free from debris can also help.

What is C0F65?

The diagnostic trouble code (DTC) C0F65 indicates a fault related to the steering angle sensor or its circuit, which is crucial for the proper functioning of advanced driver-assistance systems (ADAS). This code is often triggered in vehicles like the 2015-2018 Honda Accord, among others. When the steering angle sensor fails or sends erroneous signals, it can lead to issues such as poor steering response, erratic lane-keeping assistance, or even unexpected activation of electronic stability control systems. Car owners might notice the 'Check Engine' light illuminated on their dashboard, and in some cases, they may experience a stiff or unresponsive steering wheel, which can pose safety risks. The steering angle sensor is responsible for relaying the angle of the steering wheel to the vehicle's onboard computer, enabling systems like traction control and anti-lock brakes to operate effectively. Ignoring the C0F65 code can lead to further complications with vehicle handling and may result in costly repairs down the line. Thus, understanding the implications of this code is essential for maintaining vehicle safety and performance.

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

Symptoms

Common symptoms when C0F65 is present:

  • The 'Check Engine' light is illuminated continuously, signaling a need for diagnostic inspection.
  • Steering feels unresponsive or overly stiff, making it difficult to steer the vehicle, especially at low speeds.
  • Driver assistance features, such as lane-keeping assist or stability control, may malfunction or become disabled.
  • Unexpected steering corrections may occur, causing the vehicle to drift or sway unexpectedly.
  • Increased wear on tires, noticeable from uneven tread wear patterns due to improper wheel alignment.

Possible Causes

Most common causes of C0F65 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor may become damaged from wear and tear or exposure to moisture.
  2. Another cause could be damaged wiring or connectors in the steering system, which can lead to intermittent signals and is often overlooked during routine inspections.
  3. Improper alignment or suspension issues can also lead to incorrect readings from the steering angle sensor, contributing to the code's appearance.
  4. Less common causes include software glitches in the vehicle's control modules, which may require a software update from the manufacturer to resolve.
  5. In rare cases, a complete failure of the steering control module may occur, necessitating replacement, which can be costly.
