Wheel Speed Sensor (WSS) Signal Range/Performance Problem
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 telling the computer that one of the wheels is spinning at an unusual speed compared to the others, which could mean a sensor is faulty or there's a wiring issue.
What the computer is actually seeing
The computer expects normal wheel speed inputs that correlate with vehicle speed, typically within a range of 0 to 60 mph for accurate calculations.
What a healthy reading looks like
Wheel speed sensors should output voltage between 0.5 to 5 volts, depending on wheel speed.
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 and connectors for damage or corrosion.
- 22. Measure voltage at the wheel speed sensor harness (should be around 0.5 to 5 volts). If not, go to step 3, else replace the sensor if the wiring is good.
- 33. Confirm the sensor is clean and free of debris from the wheel hub area. Clean if necessary, otherwise proceed to step 4.
- 44. Scan the ABS module for any stored codes. If related codes exist, follow specific diagnostics for the associated systems.
- 55. Test the wheel speed sensor by removing it and simulating wheel speed with a multimeter or oscilloscope. If readings are inconsistent, replace the sensor.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- ABS module issues
- Rust or debris on sensor
- Incorrect tire size

Frequently asked questions
Is it safe to drive with this code?
It's considered moderate severity; if the ABS or traction control is affected, it's safer to fix it before driving long distances.
Will this code clear itself?
It might if the underlying issue resolves; however, it's best to diagnose and fix the root cause.
Why does this code sometimes relate to ABS problems?
The ABS system relies on accurate wheel speed readings, and any faults can trigger this code alongside ABS errors.
