What is B0476?

The diagnostic trouble code (DTC) B0476 indicates a problem with the steering wheel position sensor circuit. This sensor measures the angle of the steering wheel and sends this information to the vehicle's computer system to assist with various functions, including electronic stability control and power steering. A malfunction in the steering wheel position sensor can lead to issues with steering response, affecting the overall handling of the vehicle. This code is particularly common in vehicles like the 2013-2017 Chevrolet Malibu and the 2015-2018 Ford Mustang. When this code triggers, you might notice that your vehicle's steering feels unresponsive or erratic, which can pose safety concerns. Ignoring this issue can lead to more significant problems down the line, including the potential for steering failure. Therefore, it's crucial to address the B0476 code promptly to maintain safe driving conditions and prevent further damage to the steering system.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0476 is present:

  • The check engine light illuminates, indicating a fault in the steering wheel position sensor.
  • Steering feels loose or unresponsive, making it difficult to control the vehicle.
  • The vehicle may experience issues with electronic stability control, causing warning lights to appear on the dashboard.
  • Increased steering effort required, especially at low speeds, which can lead to driver fatigue.
  • Inconsistent steering response, where the vehicle may not follow the intended path.

Possible Causes

Most common causes of B0476 (ordered by frequency):

  1. The most common cause is a faulty steering wheel position sensor, with a likelihood of about 70%. These sensors can wear out or fail due to exposure to elements like moisture or debris.
  2. Another possible cause is damaged wiring or connectors in the steering sensor circuit, which may account for around 20% of cases. Frayed wires can lead to poor connections and erratic sensor readings.
  3. Improper installation or a malfunctioning steering column can also trigger this code, especially after recent repairs, with a 5% likelihood.
  4. Less common but serious causes include a malfunction in the electronic control module (ECM), which may require advanced diagnostic tools to identify.
  5. A rare cause could be a steering rack failure, which can affect steering performance and requires immediate attention.
