Wheel Speed Sensor Range/Performance Problem
There’s a problem with the wheel speed sensor data for one or more wheels.
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 computer is getting inaccurate or no speed data from a wheel speed sensor, which could be due to a faulty sensor or wiring issue.
What the computer is actually seeing
The system expects a wheel speed between 0 to 100 mph while the vehicle is moving, with each wheel reporting a similar speed variance.
What a healthy reading looks like
Wheel speed signal should fluctuate between 0 to 100 mph corresponding to vehicle speed; voltage signals typically range from 0.5V to 5V depending on 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. Check for any visible damage to wiring and connectors for the wheel speed sensors. Repair any issues found. Decision: If wiring is intact, move to next step.
- 22. Inspect the wheel speed sensor itself for dirt or damage. Clean or replace if necessary. Decision: If sensor looks good, proceed to check the voltage signals.
- 33. Use a multimeter to measure the voltage output from the wheel speed sensor while spinning the wheel. Expected voltage should be between 0.5V to 5V. Decision: If signal is absent or outside this range, replace the sensor.
- 44. Check the ABS module for faults using a scan tool; confirm that the module is operational and does not have internal failure. Decision: If ABS module is faulty, it needs replacement.
Common causes
- Faulty wheel speed sensor
- Wiring issues or damaged connectors
- Corrosion at sensor connections
- Faulty ABS module
- Speed sensor reluctor ring damage

Frequently asked questions
Can I still drive my vehicle with this code present?
Yes, but you may experience issues with braking and stability control systems. Get it checked as soon as possible.
Will this code come back after I clear it?
It may come back if the underlying problem isn’t fixed, like a bad sensor or wiring issue.
Why is this code related to other codes?
They often indicate the same issue but for different wheels or systems sharing the same speed data.
