This means that the car's computer is having trouble communicating with a sensor that helps measure how hard you're pressing the brake pedal.
The code C0544 indicates a problem with the circuit of the brake pressure sensor B, which might be open or not functioning correctly.
The Brake Pressure Sensor B is responsible for monitoring the pressure applied to the brake system. An open circuit or malfunction in this sensor can lead to inaccurate readings, affecting the vehicle's braking performance and safety systems.
• ABS warning light on
• Unresponsive or spongy brakes
• Inconsistent brake pedal feel
• Faulty brake pressure sensor
• Damaged wiring or connectors
• Faulty ABS control module

ABS: Anti-lock Braking System, helps prevent wheels from locking during braking.
• Check for any stored trouble codes and clear them.
• Inspect the brake pressure sensor and its wiring for damage.
• Test the sensor using a multimeter to ensure it's functioning correctly.
• Replace the faulty brake pressure sensor.
• Repair or replace damaged wiring or connectors.
