This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with a sensor that measures how hard you press the brake pedal. It's like if a video game controller's button wasn't working right.
The brake pressure sensor monitors the amount of pressure applied to the brakes. If the sensor readings are outside the expected range, the vehicle's computer triggers this code.
The C05C5 code indicates an issue with the brake pressure sensor 'F', which is responsible for providing feedback on the hydraulic pressure in the brake system. The sensor's output is not within the expected range, suggesting a potential fault in the sensor, wiring, or related components.
• ABS warning light on
• Reduced braking performance
• Unusual brake pedal feel
• Faulty brake pressure sensor
• Damaged wiring or connectors
• Malfunctioning ABS module
ABS: Anti-lock Braking System
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the brake pressure sensor and its wiring for damage.
• Test the sensor's voltage and resistance.
• Replace the brake pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ABS module if necessary.
• OBD-II scanner

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect brake system components.
• Ensure brake fluid is at the correct level.
• Schedule routine maintenance checks.
Sensor Issue
• Do not ignore the ABS warning light.
• Have the brake system inspected by a professional.
• Avoid driving in hazardous conditions until repaired.
Check with the vehicle manufacturer for warranty coverage on brake system components.
This code has been historically associated with sensor failures in vehicles with advanced braking systems.
High – Brake system issues can affect vehicle safety.
Driving with a malfunctioning brake system can be dangerous and may violate road safety regulations.
• Vehicle stationary
• Engine running
The brake pressure sensor is typically located near the master cylinder or within the ABS module.
Q: Can I drive with the C05C5 code?
A: It's not recommended to drive with this code as it can affect your braking ability.
Q: How do I reset the C05C5 code?
A: The code can be reset with an OBD-II scanner, but the underlying issue should be fixed first.
