Wheel Speed Sensor Signal Circuit Failure
Indicates a problem with the wheel speed sensor circuit.
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 reads how fast each wheel is turning. If the signal from the sensor isn’t working properly, the system can’t tell the vehicle’s speed accurately.
What the computer is actually seeing
The computer looks for a signal voltage between 0 to 5 volts coming from the wheel speed sensor. A drop to 0 volts or complete loss of signal indicates an issue.
What a healthy reading looks like
The expected voltage output from the wheel speed sensor should be between 0.5V (at low speeds) and 4.5V (at high speeds).
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 the wiring and connectors leading to the wheel speed sensor for damage or loose connections.
- 22. Test the wheel speed sensor with a multimeter. Expected voltage is between 0.5V and 4.5V when spinning the wheel manually. If reading is out of this range, replace the sensor.
- 33. Inspect the ABS control module for any fault codes or issues. If it’s throwing additional error codes, consider replacing the module before condemning the sensor again.
- 44. Clear the code and take the vehicle for a test drive to monitor wheel speed sensor operation. If the code returns immediately, further inspect the wiring harness for shorts. If it operates normally, monitor for a few days.
Common causes
- Damaged wiring or connectors to the wheel speed sensor
- Faulty wheel speed sensor
- Malfunctioning ABS control module
- Corrosion or dirt accumulation at sensor connections

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity. You may experience issues with traction control or ABS functioning properly, so repair soon.
Will this code come back after clearing?
If there's an unresolved issue with the sensor or wiring, yes, the code will likely return.
Why does this code appear with ABS issues?
The wheel speed sensor directly affects the ABS system, so a failure here can trigger ABS-related codes.
