Brake Pedal Feedback Pressure Circuit
Diagnostic & Technical Explanation
Code C0024 (Brake Pedal Feedback Pressure Solenoid 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.
These 2 diagnostic trouble codes share one
detection mechanism and one repair path, which is why MechanicDB groups them into a single
authored fault family rather than repeating the same explanation 2 times.
