Wheel Speed Sensor Range/Performance Problem
The system has detected an issue with the wheel speed sensor's performance or range.
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 measures how fast each wheel is turning. If the computer sees that the readings from this sensor are too low, too high, or inconsistent, it throws this code.
What the computer is actually seeing
The vehicle's computer monitors the wheel speed sensors to ensure they fall within expected ranges when compared to vehicle speed and other wheel sensors.
What a healthy reading looks like
Typical wheel speed signals should be between 0-5 volts, corresponding to speeds from 0 to approximately 200 km/h. Any readings outside this range can trigger the fault.
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 wheel speed sensor wiring and connectors for damage or corrosion. If found, repair or replace as needed. Decision: Is wiring/connectors okay? (Yes: go to step 2; No: repair/replace and retest)
- 22. Check for any visible debris or metal shavings on the wheel speed sensor. Clean sensor if necessary. Decision: Did cleaning help? (Yes: clear code and retest; No: go to step 3)
- 33. Use a scan tool to monitor live data from wheel speed sensors. Compare readings among all wheels. Decision: Are readings consistent? (Yes: go to step 4; No: replace faulty wheel speed sensor)
- 44. Check for any active DTCs that could affect the ABS or traction control systems. Decision: Are there any other codes? (Yes: diagnose and repair other codes; No: consider further diagnostics for calibration issues)
Common causes
- Damaged or corroded wheel speed sensor wiring
- Faulty wheel speed sensor
- Bad wheel bearing affecting sensor performance
- Poor connector contact or corrosion
- Dirty sensor tip due to debris or rust

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; it may affect traction control, so fix soon but it's drivable.
Will this code come back after clearing it?
Yes, if the underlying issue isn't fixed, the code will return.
Why does this code pair with other codes?
The wheel speed sensor impacts multiple systems, so a performance issue may trigger related codes.
