What is C0444?

DTC C0444 indicates a malfunction in the steering angle sensor, a vital component in many vehicles, particularly in models like the 2011-2019 Toyota Camry and 2013-2018 Ford Fusion. This sensor plays a crucial role in determining the position of the steering wheel, which is essential for systems like electronic stability control and advanced driver-assistance systems (ADAS). When the steering angle sensor fails or provides incorrect data, it can lead to a series of issues. Drivers may experience erratic or unresponsive steering, and warning lights on the dashboard may illuminate. Ignoring this code can lead to severe safety concerns, especially during adverse driving conditions. A malfunctioning steering angle sensor can prevent the vehicle's stability control systems from functioning correctly, which may increase the risk of skidding or losing control of the vehicle. Additionally, a failed sensor can trigger the check engine light, indicating a need for immediate attention. If you're experiencing issues related to C0444, it's essential to diagnose and address the problem promptly to maintain vehicle safety and performance.

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

Symptoms

Common symptoms when C0444 is present:

  • The check engine light remains illuminated, indicating a fault in the vehicle's system that requires attention.
  • Steering feels unresponsive or erratic, making it difficult to control the vehicle, especially in tight turns.
  • You may notice the vehicle's stability control system not engaging properly, leading to a loss of traction during adverse conditions.
  • Unusual noises from the steering column may occur, signaling potential mechanical issues in the steering assembly.
  • The vehicle may exhibit abnormal handling characteristics, such as pulling to one side or difficulty returning to center after a turn.

Possible Causes

Most common causes of C0444 (ordered by frequency):

  1. The most common cause of code C0444 is a faulty steering angle sensor, which has a likelihood of about 60%. This can occur due to wear and tear or electrical issues.
  2. Another cause can be a misalignment or damage to the steering system, which can interfere with the sensor’s readings. This is often seen in vehicles after an accident.
  3. Wiring issues, such as frayed wires or poor connections, can also lead to this error code. Regular inspections can help prevent such problems.
  4. Less commonly, a failing vehicle control module (VCM) could misinterpret signals from the steering angle sensor, although this is a rarer issue.
  5. In rare cases, software glitches in the vehicle’s onboard computer systems might trigger the C0444 code, necessitating a software update or recalibration.
