C012D Code - Brake Boost Regulation Pressure Sensor
Quick Answer
The Electronic Brake Control Module (EBCM) uses input from the boost pressure sensor for more accurate control during brake and vehicle stability enhancement system event. Common causes include Faulty Brake Pressure Modulator, Brake Pressure Modulator harness is open or shorted, Brake Pressure Modulator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
