Code C0025: Brake Pedal Feedback Pressure Sensor Circuit
Diagnostic & Technical Explanation
Code C0025 (Brake Pedal Feedback Pressure Sensor Circuit) sets when the module cannot drive or read the pedal-feel simulator circuit that pressurizes a small hydraulic chamber against the driver's foot on a brake-by-wire system, giving the pedal a conventional feel even though the master cylinder is decoupled from the wheels. A fault here means either the feedback solenoid's coil circuit is open or shorted, or the pressure sensor confirming that feedback cannot report a valid signal. Causes include a failed solenoid coil, a cracked feedback simulator seal, or corrosion at the compact connector shared by both circuits.
