This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting the right amount of power to a sensor that tells it where the brake pedal is. It's like when a remote control doesn't have enough battery power to work properly.
The code C10A3 indicates that the supply voltage to the Brake Pedal Position Sensor 'B' is lower than expected, which can affect the sensor's ability to accurately report the position of the brake pedal.
The Brake Pedal Position Sensor 'B' is part of the vehicle's braking system and helps the vehicle's computer understand how much the brake pedal is being pressed. If the supply voltage to this sensor is too low, it may not function correctly, leading to potential issues with braking performance and system diagnostics.
• Brake warning light on the dashboard
• Reduced braking performance
• Unresponsive brake pedal
• Faulty brake pedal position sensor
• Wiring issues or poor connections
• Faulty power supply to the sensor
OBD-II: On-Board Diagnostics, a standardized system for vehicle self-diagnostics.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Check the brake pedal position sensor for faults.
• Inspect wiring and connections for damage or corrosion.
• Test the voltage supply to the sensor.
• Replace the brake pedal position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Ensure proper voltage supply to the sensor.
• Multimeter
• OBD-II scanner

• Regularly inspect and maintain brake system components.
• Ensure electrical connections are clean and secure.
• Perform routine vehicle diagnostics.
Sensor Issue
• Have the brake system checked by a professional.
• Avoid heavy braking until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on brake system components.
This code is commonly associated with vehicles that have electronic brake systems and is often resolved by addressing electrical issues.
High – Brake system issues should be addressed immediately to ensure vehicle safety.
Driving with a faulty brake system can be dangerous and may lead to accidents. It is important to address this issue promptly.
• Vehicle stationary
• Engine running
The brake pedal position sensor is located near the brake pedal assembly, typically mounted on or near the brake pedal arm.
Q: Can I drive my car with this code?
A: It's not recommended to drive with a brake system issue, as it can affect braking performance and safety.
Q: How can I reset the code?
A: The code can be reset with an OBD-II scanner after the issue is fixed, but it may return if the underlying problem is not resolved.
