Braking Sensor Failure
The system detected a malfunction in the braking sensor circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The braking system is not able to read the sensor input properly, which could mean you might lose braking effectiveness or response.
What the computer is actually seeing
The computer checks the braking sensor signal and expects a steady voltage or resistance range; if this signal is missing or erratic, the fault is set.
What a healthy reading looks like
Expected sensor signal should be around 0.5 to 5 volts depending on the braking system state. Resistance should be between 1-1000 ohms when checked.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the brake fluid level; low fluid can trigger warning codes.
- 2Inspect the wiring between the braking sensor and the control module for damage or corrosion. Repair as necessary.
- 3Test the brake sensor voltage with a multimeter; should be within the expected values during operation. If not, replace the sensor.
- 4Check the connectors at both ends of the harness for tightness and corrosion; clean and repair if needed.
- 5If all tests pass and the problem persists, inspect vehicle control systems for further issues.
Common causes
- Faulty braking sensor
- Wiring issues (frayed, corroded)
- Bad connector (loose or damaged)
- Vehicle Module (BM) issue

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive with this code due to potential braking issues.
Will this code come back even if I fix it?
If the underlying issue is resolved, the code should clear and not return.
Why did this code appear after recent brake work?
Incorrect installation or new faulty parts can trigger this code; also check all connections and wiring.
