Wheel Speed Sensor Range/Performance Problem
This code indicates a problem with the wheel speed sensor circuit or signal.
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 detects how fast each wheel is spinning. If there's a problem, the computer can't accurately calculate vehicle speed or control systems like ABS properly.
What the computer is actually seeing
The computer is monitoring the voltage signal from the wheel speed sensor. It expects a smooth voltage change corresponding to wheel speed, typically around 0.5V to 4.5V, but it detects a signal that's out of range or not changing as expected.
What a healthy reading looks like
Expected voltage signal from the sensor should vary between 0.5V (stationary) to 4.5V (maximum 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. Inspect the wheel speed sensor wiring and connector for any visible damage or corrosion. If found, repair or replace as necessary, then retest.
- 22. Check the resistance of the wheel speed sensor. Expected resistance is typically between 800 to 2000 ohms. If out of range, replace the sensor.
- 33. Use a scan tool to monitor the wheel speed sensor inputs while driving. Ensure readings vary appropriately. If they remain static while moving, replace the sensor.
- 44. Inspect the sensor mounting for dirt or debris obstructing it. Clean it if necessary and retest.
- 55. If all else fails, test or replace the ABS module as the root cause.
Common causes
- Faulty wheel speed sensor
- Corroded or damaged wiring/connectors
- Contaminated sensor face
- Faulty ABS module
- Bad wheel bearing affecting sensor location

Frequently asked questions
Is it safe to drive with this code present?
It's best to fix this soon since it affects ABS and traction control, but you may drive it for a short distance carefully.
Will this code come back after clearing it?
If the issue isn’t resolved, yes, the code will likely return after clearing.
Can this code be caused by something other than the wheel speed sensor?
Yes, wiring issues or a faulty ABS module can also trigger this code.
