What is B0944?

The DTC B0944 code indicates a malfunction related to the steering angle sensor, which is crucial for determining the position of the steering wheel. This sensor plays a vital role in various systems, including stability control and advanced driver-assistance systems (ADAS). When this code appears, it typically means that the sensor is sending incorrect data to the vehicle's computer, which can affect handling and safety features. Common symptoms include warning lights on the dashboard, such as the traction control or ABS lights, and potential handling issues like increased steering effort or misalignment. If left unaddressed, a malfunctioning steering angle sensor can lead to more severe safety concerns, as it may interfere with systems designed to prevent skidding or loss of control. Regular maintenance and timely diagnostics can help avoid these problems, ensuring your vehicle remains safe and responsive. For instance, if you own a 2016-2020 Toyota Camry, understanding this code's implications can help you take proactive measures to address any steering-related issues before they escalate.

Symptoms

Common symptoms when B0944 is present:

  • The dashboard displays warning lights like ABS or traction control, indicating potential issues with stability systems.
  • The steering feels overly stiff or loose, making it difficult to control the vehicle, especially during turns.
  • You might notice irregularities in the vehicle's handling, such as drifting to one side or requiring constant corrections while driving straight.
  • There may be a noticeable delay in steering response, affecting your ability to maneuver the vehicle safely.
  • In some cases, the vehicle's stability control system may become disabled, increasing the risk of skidding during adverse conditions.

Possible Causes

Most common causes of B0944 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor itself, which accounts for about 60% of B0944 occurrences. This sensor can wear out due to age or exposure to contaminants.
  2. Another frequent issue is related wiring or connectors, which may become damaged or corroded, causing intermittent signal failures between the sensor and the vehicle's computer.
  3. A misalignment of the steering wheel can also trigger this code, often due to improper installation of the steering column or suspension components, making regular alignment checks essential.
  4. Less common but serious causes may include issues with the vehicle's electronic control unit (ECU), which can fail or have software glitches affecting sensor readings.
  5. Rarer causes could involve structural damage to the steering column from an accident, requiring extensive repairs to restore functionality.
