What is B03D2?
The diagnostic trouble code (DTC) B03D2 indicates a malfunction in the steering angle sensor, which is a critical component for stability control and advanced driver-assistance systems (ADAS). This sensor measures the angle of the steering wheel and sends this data to the vehicle's computer systems to help maintain control during driving. When B03D2 is triggered, it typically suggests that the steering angle sensor is not functioning correctly, which can lead to various issues such as loss of traction control, potential safety hazards, and diminished handling performance. Commonly found in models like the 2016-2021 Ford Explorer, this code can arise from a range of problems including wiring issues, sensor failure, or alignment discrepancies. If left unaddressed, it can significantly impact vehicle safety and performance, necessitating immediate attention. It's essential to diagnose the issue accurately to determine whether a simple recalibration or a more complex repair is required. Understanding this code is crucial for maintaining optimal vehicle performance and ensuring a safe driving experience.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B03D2 is present:
- Check engine light remains illuminated, indicating an issue that needs attention.
- Vehicle handling feels off; steering may feel unresponsive or loose, especially during turns.
- Traction control warning light may activate, indicating potential loss of traction control functionality.
- Increased difficulty in aligning the steering wheel; may require frequent adjustments.

Possible Causes
Most common causes of B03D2 (ordered by frequency):
- Faulty steering angle sensor - This is the most common cause, with a likelihood of about 60%. A malfunctioning sensor often results from internal failure or wear.
- Wiring issues - Damaged or corroded wiring can disrupt the signal between the sensor and the vehicle's computer, accounting for approximately 25% of cases.
- Alignment problems - Misalignment can lead to inaccurate readings from the steering angle sensor, contributing to around 10% of B03D2 occurrences.
- Less common but serious cause includes a malfunctioning ABS module, which can greatly affect braking and control systems.
- Rare but possible cause could be software issues in the vehicle’s computer systems that may require a software update or reprogramming.
