Wheel Speed Sensor Range/Performance Problem
The system has detected an issue with one or more wheel speed sensors.
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)
Your vehicle is monitoring the speed of each wheel to help with stability and traction. If it sees a wheel that’s not spinning correctly, it triggers this code.
What the computer is actually seeing
The ABS control module expects each wheel's speed to be within a certain range relative to the others, typically around 0-255 km/h (0-160 mph).
What a healthy reading looks like
Expected wheel speed should be within 5 km/h (3 mph) of each other at 20-80 km/h (12-50 mph).
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 wiring and connectors to the wheel speed sensors for damage or corrosion. Repair if necessary. Decision: If damaged wiring is found, repair it and clear the code. If okay, move to step 2.
- 22. Check the integrity of the wheel speed sensors using a multimeter; measure the output voltage while spinning the wheel. You should get around 0.5-5 volts depending on speed. Decision: If the voltage is out of spec, replace the faulty sensor. If okay, move to step 3.
- 33. Inspect the tone rings for cracks or missing teeth. If damaged, replace the tone ring. Decision: If replaced, clear the code and retest. If okay, move to step 4.
- 44. Scan for other codes that may indicate brake system issues. Address any additional faults accordingly. Decision: If there are no other codes, you may have a more complex internal module fault requiring deeper diagnostics.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Absence of a wheel speed signal due to a broken tone ring
- Brake system issues affecting wheel rotation

Frequently asked questions
Is it safe to drive with this code?
It's manageable but fix it soon because it affects stability control and ABS functionality.
Will this problem return after I fix it?
If the root cause is fixed, it should not return; otherwise, you risk recurring issues.
Why does this code seem related to other codes?
Many wheel speed sensors share wiring and can be affected by similar faults, leading to multiple codes triggering together.
