C0131 Code - Traction Control System Pressure Circuit
Quick Answer
The Electronic Brake Control Module (EBCM) monitors the brake pressure sensor which is integral to the Brake Pressure Modulator Valve (BPMV). Common causes include Faulty Electronic Brake Control Module (EBCM) with Brake Pressure Modulator Valve (BPMV), Electronic Brake Control Module harness is open or shorted, Electronic Brake Control Module 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.
