This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a weak signal from the brake pressure sensor, which helps it know how hard you're pressing the brake pedal.
The brake pressure sensor measures the force applied to the brake pedal and sends this information to the vehicle's computer. A 'circuit low' code indicates that the signal from the sensor is weaker than expected.
The C064F code is set when the Electronic Brake Control Module (EBCM) detects a low voltage signal from the brake pressure sensor circuit. This could be due to an electrical issue such as a short or open circuit, or a faulty sensor.
• ABS warning light on
• Brake warning light on
• Reduced braking performance
• Faulty brake pressure sensor
• Damaged wiring or connectors in the sensor circuit
• Faulty Electronic Brake Control Module (EBCM)
EBCM: Electronic Brake Control Module
ABS: Anti-lock Braking System
• Use a scan tool to confirm the code and check for other related codes.
• Inspect the brake pressure sensor and its wiring for damage.
• Test the brake pressure sensor with a multimeter for proper voltage.
• Replace the brake pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the Electronic Brake Control Module if necessary.
• OBD-II scan tool
• Multimeter
• Basic hand tools

• Regularly inspect brake system components.
• Keep electrical connections clean and secure.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore the ABS warning light.
• Have the brake system checked by a professional.
• Avoid heavy braking until the issue is resolved.
Check with your vehicle manufacturer for brake system warranty coverage.
This code has been associated with vehicles experiencing intermittent ABS issues due to sensor or wiring faults.
High – Brake system issues should be addressed immediately to ensure safe vehicle operation.
Driving with a malfunctioning brake system can be dangerous and is not recommended. Ensure repairs are performed by a qualified technician.
• Vehicle stationary with ignition on.
• Brake pedal pressed to simulate sensor operation.
The brake pressure sensor is usually located near the master cylinder or integrated into the ABS module.
Q: Can I drive with the C064F code?
A: It's not recommended to drive with this code active, as it may affect braking performance.
Q: How do I reset the C064F code?
A: After repairs, use an OBD-II scan tool to clear the code from the vehicle's computer.
