The car's computer is saying that the sensor that checks how hard you press the brake pedal is getting a signal that's too strong.
The brake pressure sensor monitors the pressure applied to the brakes. A 'circuit high' code means the sensor is receiving a voltage signal higher than expected.
The C064E code indicates that the brake pressure sensor N is reporting a voltage signal that is above the acceptable range set by the vehicle's manufacturer. This could be due to a short circuit, a faulty sensor, or an issue with the vehicle's wiring.
• Check for other related codes and clear them to see if they return.
• Inspect the brake pressure sensor and its wiring for damage.
• Test the sensor voltage with a multimeter to confirm it is out of range.
• Replace the faulty brake pressure sensor.
• Repair or replace damaged wiring or connectors.
• Replace the ECU if it is determined to be faulty.

• Regularly inspect brake components for wear and damage.
• Ensure all electrical connections are secure and free of corrosion.
• Have the braking system checked during routine maintenance.
Sensor Issue
• Do not ignore the brake warning light; have it checked immediately.
• Drive cautiously if the ABS light is on, as braking performance may be affected.
Check with your vehicle manufacturer as brake system components may be covered under warranty.
This code has been more commonly reported in vehicles with higher mileage where wear and tear on brake components is more prevalent.
High – Braking is a critical safety feature. Immediate attention is required to ensure safe operation of the vehicle.
Driving with a malfunctioning brake system can lead to accidents. It is illegal and unsafe to drive a vehicle with known brake issues.
• Vehicle must be in a safe, stationary position.
• Ensure the ignition is in the 'on' position without starting the engine.
The brake pressure sensor is typically located near the master cylinder or integrated within the ABS module.
Q: Can I drive my car with the C064E code?
A: It's not recommended as it may affect your braking performance. Have it checked by a professional as soon as possible.
Q: How do I reset the C064E code?
A: After repairing the issue, you can use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
