This summary uses the existing diagnostic information shown in full below.
This means that a sensor that helps the car understand how much you are pressing the brake pedal is not working properly.
The brake booster travel sensor measures how far the brake pedal is pushed and sends this information to the car's computer. If the circuit is high, it means the sensor is sending too much voltage or is not working correctly.
The C0570 code indicates a problem with the brake booster travel sensor circuit, specifically that the voltage level is higher than expected. This could be due to a short circuit, a faulty sensor, or a wiring issue.
• Brake warning light on the dashboard
• Inconsistent brake pedal feel
• ABS system may be disabled
• Faulty brake booster travel sensor
• Wiring issues such as short circuits or open circuits
• Faulty or corroded connectors
Brake Booster: A component that helps increase the force applied to the brake pedal.
Circuit High: A condition where the voltage is higher than expected in an electrical circuit.
• Use an OBD-II scanner to confirm the code.
• Inspect the brake booster travel sensor and its wiring for damage.
• Check the connectors for corrosion or looseness.
• Replace the brake booster travel sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools (screwdrivers, wrenches)

• Regularly inspect brake system components.
• Ensure connectors are clean and secure.
• Avoid harsh driving conditions that could damage wiring.
Sensor Issue
• Have your vehicle inspected by a professional if you notice braking issues.
• Do not ignore the brake warning light on your dashboard.
Check with your vehicle manufacturer for warranty coverage on brake system components.
This code has been associated with vehicles that have electronic brake control systems, particularly in models from the mid-2000s onwards.
High – Brake system issues can affect vehicle safety and should be addressed promptly.
Driving with a malfunctioning brake system can be dangerous and may violate road safety regulations.
• Vehicle stationary with engine on
• Brake pedal operation
The brake booster travel sensor is typically located near the brake pedal or within the brake booster assembly.
Q: Can I drive with a C0570 code?
A: It's not recommended to drive with this code active as it may indicate a problem with the braking system.
Q: How do I clear the C0570 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
