Wheel Speed Sensor Range/Performance Problem
This code indicates a malfunction or performance issue with the wheel speed sensor.
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 one sensor isn't working or is sending weird signals, it can throw this code.
What the computer is actually seeing
The vehicle's computer expects a smooth signal from the wheel speed sensor, typically around 0-12 volts depending on the speed. If the signal drops too low or too high, or is inconsistent, this code sets.
What a healthy reading looks like
Sensor voltage should range from 0.5V (stationary) to about 12V (spinning), expected to change smoothly as wheel speed increases or decreases.
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 obvious damage or corrosion on the wheel speed sensor wiring and connector. Repair as needed. Decision: Are there visible signs of damage? Yes: Repair wiring. No: Proceed.
- 22. Measure the voltage at the wheel speed sensor connector with the vehicle in motion. Expected range is 0.5V to 12V. Decision: Is the voltage within range? Yes: Sensor is likely fine. No: Replace sensor.
- 33. Check all four wheel speed sensors using a scan tool; watch for any sensor showing a vastly different reading than others. Decision: Is one sensor significantly lower than the others? Yes: Replace that wheel speed sensor. No: Proceed.
- 44. Inspect the ABS module for any diagnostic trouble codes or performance issues. Decision: Are there additional codes present? Yes: Address those codes first. No: Clear codes and take the vehicle for a test drive.
Common causes
- Faulty wheel speed sensor
- Wiring issue or corrosion around the sensor connector
- Damaged ABS module
- Incorrectly sized tires affecting speed readings

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, so it's best to fix soon. You might experience issues with traction control and ABS.
Will this code come back after clearing?
If the underlying issue isn't fixed, yes, it will likely return.
Why do I see this with other codes?
It often pairs with other wheel speed sensor or ABS codes due to interconnected systems.
