C0204 Saturn Code - Master Cylinder Pressure Sensor
Quick Answer
The Electronic Brake Control Module (EBCM) uses the input from the master cylinder pressure sensor for more accurate braking control during a vehicle stability enhancement system (VSES) event. Common causes include Faulty Master Cylinder Pressure Sensor, Master Cylinder Pressure Sensor harness is open or shorted, Master Cylinder Pressure Sensor 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.
