C064D code meaning
Brake Pressure Sensor N Circuit/Open
What C064D means
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.
C064D at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C064D
- ABS/ESC warning lamp on, often with other pressure sensor codes
- Stability control and brake assist unavailable
Common causes of C064D
- Most likelyOpen in a line or plug shared by several sensors
- PossiblePoor contact at the sensor plug or spring contact
- Less likelyInternal interruption in sensor N
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4D | The exact fault in that area. |
What to do next
- Note C064D and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C064D
What does C064D mean?
C064D means "Brake Pressure Sensor N Circuit/Open". C064D concerns an interrupted circuit at brake pressure sensor N, the thirteenth of the series. It is a generic code, so it means the same on every make.
Is it safe to drive with C064D?
Drive gently and only to a workshop. With C064D the car can go into limp mode (reduced power) to protect itself.
Will C064D fail an emissions test?
C064D is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C064D to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C064D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
