This summary uses the existing diagnostic information shown in full below.
This code means that a sensor that helps control a part of the car that moves to make it more aerodynamic is getting too much electrical power.
The code B3A46 indicates that the position sensor for an active aerodynamic feature is receiving a higher voltage than expected.
The active aerodynamic system in a vehicle includes components that adjust to improve airflow and vehicle performance. The position sensor 2 monitors the position of one of these components. A 'circuit high voltage' error suggests that the sensor is receiving a higher voltage than it should, which could be due to a wiring issue, a faulty sensor, or a problem with the control module.
• Warning light on the dashboard
• Reduced aerodynamic performance
• Unusual noises from the aerodynamic components
• Faulty position sensor
• Wiring issues such as shorts or open circuits
• Malfunctioning control module
Aerodynamic: The way air moves around things.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Check for any other related error codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the position sensor with a multimeter to verify voltage levels.
• Replace the faulty position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regular maintenance checks
• Ensure wiring is secure and free from damage
• Avoid exposure to extreme conditions that could affect sensors
Sensor Issue
• Have the vehicle inspected by a professional if this code appears.
• Avoid high-speed driving until the issue is resolved.
Check with the vehicle manufacturer for specific warranty coverage on aerodynamic components.
This code has been associated with vehicles that have advanced aerodynamic systems, particularly in high-performance models.
Moderate – It should be addressed soon to ensure optimal vehicle performance.
Ignoring this issue could lead to reduced vehicle performance and efficiency.
• Vehicle at operating temperature
• Aerodynamic system activated
The position sensor is typically located near the active aerodynamic component it monitors, such as a spoiler or grille.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to reduced vehicle performance and efficiency, and potentially more costly repairs in the future.
Q: Can I drive my car with this code?
A: While you can drive your car, it's recommended to have it checked soon to avoid potential performance issues.
