This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that tells it where the brake pedal is pushed too high. It's like when a game controller's button is stuck and always thinks you're pressing it.
The Brake Pedal Position Sensor A is sending a signal to the car's computer that is higher than expected, indicating a possible issue with the sensor or its circuit.
The P057D code is triggered when the Powertrain Control Module (PCM) detects an unusually high voltage from the Brake Pedal Position Sensor A. This sensor helps the vehicle determine the position of the brake pedal. A high circuit condition could be due to a short to voltage, an open circuit, or a faulty sensor.
• Brake lights may not function properly
• Cruise control may not work
• ABS light may illuminate
• Faulty Brake Pedal Position Sensor
• Wiring issues such as a short to voltage or open circuit
• Faulty PCM (rare)
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors of the brake pedal position sensor.
• Test the brake pedal position sensor for proper voltage and resistance.
• Replace the Brake Pedal Position Sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reset the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II Scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular inspection of brake system components.
• Ensure wiring and connectors are not exposed to moisture.
• Regularly test brake lights and cruise control functionality.
Sensor Issue
• Do not ignore the brake warning lights on your dashboard.
• Have the brake system checked by a professional if you notice any issues.
Check if the vehicle's warranty covers brake system components.
This code has been more commonly reported in vehicles with higher mileage or those exposed to harsh environmental conditions.
Moderate – While the vehicle may still be drivable, brake system issues should be addressed promptly to ensure safety.
Driving with a malfunctioning brake system can be dangerous and may violate traffic safety laws.
• Vehicle must be on a level surface.
• Ensure the ignition is in the ON position without starting the engine.
The Brake Pedal Position Sensor is typically located near the brake pedal assembly inside the vehicle cabin.
Q: Can I drive my car with a P057D code?
A: It is not recommended to drive with this code as it may affect the brake lights and cruise control, potentially leading to unsafe driving conditions.
Q: How do I reset the P057D code?
A: After repairs, use an OBD-II scanner to clear the code, then test drive the vehicle to ensure the issue is resolved.
