What is C0A35?

The diagnostic trouble code (DTC) C0A35 indicates a problem with the steering angle sensor in many vehicles, particularly in models like the 2015-2019 Ford F-150. This code suggests that the steering angle sensor is either malfunctioning or is not communicating properly with the vehicle’s engine control module (ECM). This can lead to various issues, including difficulty in steering, erratic steering behavior, and potentially compromised safety features such as electronic stability control (ESC). When C0A35 is triggered, the vehicle may enter a 'limp' mode, where power steering assistance is reduced, making it harder for the driver to maneuver the vehicle, especially at low speeds. Ignoring this code can lead to further complications, including damage to the steering system and a decrease in overall vehicle control. To ensure safety and reliability, it is crucial to address this issue promptly. Regular maintenance checks, including the calibration of the steering angle sensor, can prevent the occurrence of such codes. If you notice any symptoms associated with C0A35, it’s advisable to seek professional assistance as soon as possible.

Symptoms

Common symptoms when C0A35 is present:

  • The check engine light illuminates and remains lit, indicating a fault in the steering system.
  • Drivers may experience difficulty in steering, particularly at low speeds, making it hard to control the vehicle.
  • You may notice that the steering feels unusually stiff or loose, affecting your ability to steer accurately.
  • The vehicle may enter limp mode, where power steering assistance is reduced, especially during tight maneuvers.
  • Unusual noises from the steering column may indicate sensor malfunction or related issues.

Possible Causes

Most common causes of C0A35 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which occurs in about 70% of cases. This sensor can wear out or become misaligned, leading to inaccurate readings.
  2. Another common cause is damaged wiring or poor connections in the steering system. This can lead to intermittent communication issues with the ECM.
  3. Improper installation of aftermarket components, such as steering wheels or electronic modifications, can also trigger C0A35. Ensure all installations are performed correctly.
  4. Less common but serious causes include a malfunctioning power steering control module, which can affect the entire steering system.
  5. In rare cases, issues may stem from a failing ECM, which can misinterpret sensor data and lead to multiple diagnostic trouble codes.
