What is B0670?
The diagnostic trouble code B0670 indicates a problem with the steering wheel position sensor circuit. This sensor plays a critical role in various vehicle systems, particularly those related to safety and stability. When the steering wheel position sensor fails or reports inaccurate readings, it can lead to issues with vehicle handling, activation of stability control systems, and even affect the overall power steering performance. Real-world implications include the potential for a loss of steering control, which significantly increases the risk of accidents. This code is commonly found in vehicles like the 2013-2018 Ford Fusion and 2010-2017 Chevrolet Equinox, among others. Drivers may experience symptoms such as the steering wheel being unresponsive or erratic, and the check engine light illuminating. Ignoring this code can lead to further complications, including additional wear on steering components and costly repairs down the line. Therefore, it’s essential for car owners to understand the implications of DTC B0670 and seek timely diagnosis and repair.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0670 is present:
- The check engine light stays on constantly, indicating a potential fault with the steering system.
- Steering feels loose or unresponsive, making it difficult to maintain control of the vehicle.
- The vehicle's stability control system may engage unexpectedly, causing erratic handling.
- Warning messages may appear on the dashboard related to steering assist or control.
- Increased wear on tires due to uneven steering input, which can lead to premature tire replacement.
Possible Causes
Most common causes of B0670 (ordered by frequency):
- The most common cause of B0670 is a faulty steering wheel position sensor, with a likelihood of 60%. This sensor may fail due to wear over time or exposure to environmental elements.
- A second cause can be damaged wiring or connectors in the steering system, which can lead to intermittent signals being sent to the vehicle's computer.
- Thirdly, a malfunctioning power steering control module can lead to inaccurate readings from the sensor, and regular checks and maintenance can help prevent this.
- Less common but serious causes might include issues with the vehicle's electronic control unit (ECU), which could lead to broader electrical problems.
- A rare cause could be a software glitch within the vehicle's onboard systems, which may require a software update or reprogramming.
