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 a sensor that measures how hard you're pressing the brake pedal.
The brake pressure sensor monitors the pressure applied to the brakes and sends this information to the vehicle's computer. A 'Circuit Low' code indicates that the voltage signal from the sensor is below the expected range.
The C053E code is triggered when the vehicle's control module detects a low voltage signal from the brake pressure sensor 'A' circuit. This sensor is responsible for providing data on the hydraulic pressure in the brake system, which is crucial for the proper functioning of the anti-lock braking system (ABS) and other related systems.

OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the brake pressure sensor and its wiring for damage or corrosion.
• Test the sensor's voltage output with a multimeter.
• Replace the brake pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the ABS control module if necessary.

• GMC Sierra
• Cadillac Escalade
• Regularly inspect brake system components.
• Keep electrical connections clean and corrosion-free.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore the ABS warning light.
• Have the brake system inspected by a professional.
• Avoid hard braking until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on brake system components.
This code has been associated with issues in vehicles equipped with advanced braking systems, particularly in models with high mileage.
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 safety regulations.
• Vehicle at operating temperature
• Brakes applied under normal driving conditions
The brake pressure sensor is typically located near the brake master cylinder or integrated into the ABS module.
Q: Can I drive with the C053E code?
A: It's not recommended to drive with this code active, as it may affect braking performance.
Q: How do I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
Pro · Four-system diagnostics
A handheld scanner aimed at engine, transmission, ABS, and airbag diagnostic work.
Chassis and ABS faults usually need a scanner that can read brake-system data directly.
