What is C08C0?

The DTC C08C0 diagnostic trouble code indicates an issue with the steering assist system, often relating to the electric power steering (EPS) module or its components. When this code is triggered, it typically means that the vehicle's onboard computer has detected a malfunction in the steering assist function. This can result in a loss of power steering assistance, making the steering feel heavy and difficult to turn, especially at low speeds. The C08C0 code is frequently seen in vehicles like the 2015-2018 Honda Accord, but may also affect other models equipped with similar EPS systems. When the code activates, you may notice the check engine light and possibly a warning message on your dashboard. Ignoring this code could lead to increased steering effort and potential safety hazards while driving. It’s important to address this issue promptly as it can affect vehicle maneuverability and overall driving safety. In many cases, a malfunctioning EPS module or a problem with the steering column assembly can lead to this code, necessitating comprehensive diagnostics and possibly replacement components to restore functionality.

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

Symptoms

Common symptoms when C08C0 is present:

  • The check engine light remains illuminated, signaling the need for diagnostics.
  • Steering feels unusually heavy, especially during low-speed maneuvers, making parking and turning difficult.
  • Intermittent loss of steering assist, where the steering may feel normal one moment and heavy the next.
  • Unusual noises coming from the steering column, such as clicking or grinding sounds while turning.
  • A warning message may appear on the dashboard, indicating a steering system malfunction.

Possible Causes

Most common causes of C08C0 (ordered by frequency):

  1. The most common cause of the C08C0 code is a faulty electric power steering (EPS) module, which occurs in about 60% of cases. This module is responsible for providing the necessary assist, and any internal failures can trigger the code.
  2. Another frequent cause is issues with the steering angle sensor, which provides critical input to the EPS system about steering position. If this sensor fails or becomes misaligned, it can lead to steering assist problems.
  3. Wiring issues such as frayed or corroded connections in the EPS system can also result in the C08C0 code. Regular inspections can prevent these issues by identifying wear and tear early.
  4. Less commonly, a failing power steering pump could contribute to the C08C0 code, particularly in older vehicles where pump wear is more prevalent.
  5. In rare cases, software glitches in the vehicle's onboard computer can trigger this code, necessitating a software update or reprogramming to resolve.
