This summary uses the existing diagnostic information shown in full below.
The car's computer doesn't know where the brake pedal is when you press it.
The vehicle's control module has not successfully learned or calibrated the position of the brake pedal.
The C05C0 code indicates that the brake pedal position sensor has not been properly calibrated or learned by the vehicle's control module. This sensor is crucial for various systems, including the anti-lock braking system (ABS) and electronic stability control (ESC), as it provides data on the position of the brake pedal.
• ABS warning light illuminated
• Reduced braking performance
• Unresponsive brake pedal
• Faulty brake pedal position sensor
• Incorrect calibration procedure
• Faulty wiring or connectors
Brake Pedal Position Sensor: A sensor that detects the position of the brake pedal to assist in braking functions.
Calibration: The process of setting or correcting a measuring device or base level.
• Check for other related codes.
• Inspect the brake pedal position sensor and its wiring.
• Perform a brake pedal position sensor calibration.
• Replace the brake pedal position sensor if faulty.

Sensor Issue
• Have the vehicle inspected by a professional if the ABS light is on.
• Do not ignore the warning light as it affects braking safety.
Check with your vehicle manufacturer for specific warranty coverage on brake components.
This code has been more prevalent in vehicles with electronic brake systems introduced in the early 2000s.
High – Affects braking performance and safety.
Driving with a malfunctioning brake system can lead to accidents and is not safe.
• Vehicle stationary
• Ignition on
