C064DBrake Pressure Sensor N Circuit/Open
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C064D concerns an interrupted circuit at brake pressure sensor N, the thirteenth of the series. Larger sensor counts push makers towards digital links. A Bosch patent proposes PSI5 or DSI current interfaces on which up to four pressure sensors share two wires for power and data; an open in such a pair would silence every sensor on it at once. SENT sensors, which Pico Technology shows with two pressure channels in one housing, can likewise lose two readings through one broken line. Continental's integrated module groups several sensors under one combined plug with the pump motor. Hence: if several pressure codes appear together, look for the common line or plug. No carmaker publishes C064D or assigns the letter N.
