Wheel Speed Sensor Circuit Fault
There’s 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 measures how fast the wheels are spinning, and this code means there's an issue in the wiring or sensor.
What the computer is actually seeing
The computer compares the expected voltage (around 0.5V at rest) from the wheel speed sensor to the actual voltage it receives. If it sees a big difference or no signal at all, it triggers this code.
What a healthy reading looks like
Expected voltage from a functioning wheel speed sensor is about 0.5V at rest and should fluctuate between 0.5V to 4.5V when spinning.
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.
- 1Check the physical condition of the wheel speed sensor and its connector. Make sure there's no damage or debris.
- 2Use a multimeter to check for continuity in the wiring from the sensor to the module. Look for a resistance of less than 5 ohms.
- 3Inspect the sensor output voltage at the connector with the key on and engine off. It should read around 0.5 volts. If not, replace the sensor if wiring is okay.
- 4If everything checks out, consider testing the ABS module for faults, as it might be the issue.
Common causes
- Failed wheel speed sensor
- Damaged wiring or connectors
- Faulty ABS module
- Poor ground connection

Frequently asked questions
Can I still drive the vehicle with this code?
Yes, but be aware that your traction control and ABS might not function properly.
Will this code come back after I clear it?
It may return if the underlying issue isn’t fixed or if the sensor is faulty.
Why does this code show up with other codes?
It's common as multiple systems in the ABS rely on wheel speed sensor data; if one fails, it can affect others.
