What vehicles are most commonly affected by B0466?
DTC B0466 frequently affects models like the 2014-2020 Honda Accord, 2016-2021 Toyota Camry, and 2015-2020 Ford Fusion. Always check for any recalls or technical service bulletins related to your vehicle.
How can I prevent B0466 from happening again?
Regularly inspect your vehicle's wiring and connectors, keep them clean and free from corrosion, and promptly address any dashboard warning lights to minimize the chances of encountering DTC B0466.
What is B0466?
DTC B0466 refers to a fault in the steering angle sensor circuit, commonly found in vehicles like the 2014-2020 Honda Accord, but can also affect other models equipped with electronic stability control systems. The steering angle sensor measures the angle of the steering wheel and communicates this data to the vehicle's onboard computer. This information is crucial for various systems, including traction control, electronic stability control, and adaptive cruise control. When this code appears, it indicates that the steering angle sensor is malfunctioning or that there is an issue with the circuit, leading to the potential for erratic handling or loss of control under certain conditions. In practical terms, if your vehicle displays this code, you may notice that the stability control light is illuminated on your dashboard, and your vehicle might not respond as expected during cornering or slippery conditions. Ignoring this code could lead to safety issues, making it essential to address it promptly to ensure optimal vehicle performance and safety.

Symptoms
Common symptoms when B0466 is present:
- Check engine light or stability control light stays illuminated, indicating a fault in the steering angle sensor.
- Vehicle experiences unpredictable handling, particularly during sharp turns or sudden maneuvers.
- The steering feels unresponsive or overly sensitive, making it difficult to control the vehicle smoothly.
- Reduced effectiveness of stability control systems, leading to potential skidding in slippery conditions.
- Inconsistent or erratic behavior of the cruise control system, which may disengage unexpectedly.
Possible Causes
Most common causes of B0466 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, with a likelihood of about 60%. This might occur due to wear and tear over time or exposure to moisture.
- A damaged wiring harness or loose connections can cause the sensor to malfunction, accounting for roughly 25% of cases. Regular inspections can help identify and prevent wiring issues.
- Corrosion at connectors can lead to intermittent faults in the sensor circuit, making up about 10% of problems. Keeping connectors clean and well-maintained is essential.
- Less common but serious causes include issues with the vehicle's electronic control unit (ECU), which may require professional diagnosis.
- Rarely, software glitches in the vehicle’s system can cause false error codes, necessitating a software update from a dealership.
