Wheel Speed Sensor Range Performance Problem
The ABS control module detects an issue with a wheel speed sensor's signal 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 ABS module thinks a wheel speed sensor is giving faulty readings, which can cause issues with vehicle traction control and ABS operation.
What the computer is actually seeing
The ABS control module monitors the voltage signal from each wheel speed sensor. If the voltage is too low or too high outside the expected range, it triggers a code.
What a healthy reading looks like
Wheel speed sensor outputs should be around 0-5 V, varying with wheel rotation 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 all associated wiring and connectors for damage or corrosion. Repair as necessary. Decision point: Did you find any wiring issues? If yes, fix the wiring. If no, proceed to step 2.
- 22. Using a scanner, monitor the wheel speed sensor output while the vehicle is moving. It should change in real-time with wheel movement. Decision point: Is the signal fluctuating correctly? If yes, go to step 3. If no, replace the affected wheel speed sensor.
- 33. Test the ABS control module for fault codes related to the speed sensors, usually found under ABS or traction control. Decision point: Are there related codes? If yes, troubleshoot according to those codes. If no, further diagnose the ABS control module.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Corrosion at connectors
- Faulty ABS control module

Frequently asked questions
Is it safe to drive with this code?
It's safe to drive, but ABS and traction control may be unreliable, especially in slippery conditions.
Will this code come back after clearing?
If the underlying issue is unresolved, the code is likely to return after clearing.
Why does this code sometimes pair with another code?
Different wheel speed sensor issues can occur at the same time, indicating multiple sensors or system problems.
