Wheel Speed Signal Fault
There’s an issue with the wheel speed sensor signal.
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 wheel speed sensor is not sending the right information to the computer, which can mess up how the brakes or traction control work.
What the computer is actually seeing
The ABS module detects that the wheel speed sensor signal is intermittent or out of the expected range, which could cause issues with anti-lock braking and traction control systems.
What a healthy reading looks like
The wheel speed should be within a range of 0-100 mph; typically around 20-30 mph during regular driving conditions.
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. Start with a visual inspection of the wheel speed sensor and its wiring for any obvious damage or corrosion.
- 22. Check the wheel speed sensor connector for secure fit and measure resistance across the terminals; should be less than 100 ohms.
- 33. Use a scan tool to view live wheel speed sensor data while the vehicle is in motion; each wheel should read similar speeds.
- 44. If one wheel's speed differs significantly from its counterparts, consider replacing that wheel speed sensor.
- 55. Recheck connectors and wiring for the affected wheel; repair or replace as needed based on inspection.
Common causes
- Corroded or damaged wheel speed sensor connectors
- Faulty wheel speed sensor
- Issues with the wiring harness or short circuits
- Wheel bearing noise or damage affecting sensor operation
Typical repair cost
