Wheel Speed Sensor Circuit Failure
Indicates a failure in the wheel speed 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 system isn’t getting proper signals from the wheel speed sensor, which helps control things like traction and stability.
What the computer is actually seeing
The computer detects an abnormal voltage or lack of signals coming from the wheel speed sensor, typically less than 0.5V or inconsistent signals during wheel rotation.
What a healthy reading looks like
Voltage should be between 0.5V and 12V, with a consistent signal that varies as wheel speed changes.
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.
- 11. Inspect the wheel speed sensor wiring for damage or disconnection. Decision: Is there visible damage? If yes, repair wiring; if no, proceed to step 2.
- 22. Check the wheel speed sensor connector for corrosion or poor contact. Decision: Is the connector corroded? If yes, clean or replace the connector; if no, proceed to step 3.
- 33. Measure the voltage at the wheel speed sensor harness while the vehicle is in motion. Decision: Is the voltage within the expected 0.5V to 12V range? If no, replace the wheel speed sensor; if yes, proceed to step 4.
- 44. Scan for additional fault codes, especially related to the ABS module. Decision: Are there any additional related codes? If yes, troubleshoot based on those codes; if no, replace the ABS module.
Common causes
- Damaged wheel speed sensor wiring
- Faulty wheel speed sensor
- Corrosion in the connector
- ABS module issues
