This summary uses the existing diagnostic information shown in full below.
This means the car's computer is getting a signal from the brake pedal sensor that is too low. It's like if you were trying to listen to music, but the volume was too low to hear anything.
The brake pedal position sensor sends a voltage signal to the car's computer to indicate the position of the brake pedal. If this voltage is too low, it triggers the C10BB code.
The C10BB code is set when the brake pedal position sensor 'A' sends a voltage signal to the Powertrain Control Module (PCM) that is below the expected range. This could indicate a problem with the sensor itself, the wiring, or the connections.
• Brake lights may not function properly
• ABS warning light may illuminate
• Brake pedal may feel different
• Faulty brake pedal position sensor
• Wiring issues or poor connections
• Faulty PCM
PCM: Powertrain Control Module
ABS: Anti-lock Braking System
• Scan the vehicle for codes and freeze frame data
• Inspect the brake pedal position sensor and wiring
• Test the sensor's voltage output with a multimeter
• Replace the brake pedal position sensor
• Repair or replace damaged wiring
• Reprogram or replace the PCM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect brake system components
• Ensure proper maintenance of electrical connections
• Avoid exposure to excessive moisture
Sensor Issue
• Do not ignore the warning light
• Get the vehicle checked by a professional
• Avoid driving if brake performance is compromised
Check with the vehicle manufacturer for warranty coverage on sensor components.
This code has been associated with issues in vehicles with electronic brake systems, particularly as vehicles age.
Moderate – It is important to address this issue to ensure proper brake function.
Driving with malfunctioning brake components can be dangerous and may violate safety regulations.
• Ignition on, engine off
• Brake pedal not pressed
The brake pedal position sensor is typically located near the brake pedal assembly.
Q: Can I drive with a C10BB code?
A: It's not recommended to drive with this code active, as it may affect brake performance.
Q: How do I reset the C10BB code?
A: The code can be reset with an OBD-II scanner after the issue is fixed.
Pro · Four-system diagnostics
A handheld scanner aimed at engine, transmission, ABS, and airbag diagnostic work.
Chassis and ABS faults usually need a scanner that can read brake-system data directly.
