Wheel Speed Sensor Malfunction
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 each wheel is turning. If it fails, the car's stability control and anti-lock brakes can get confused, affecting safety.
What the computer is actually seeing
The computer expects a voltage signal between 0 to 5 volts, indicating wheel speed. A malfunction could show as a constant voltage, no voltage, or erratic readings.
What a healthy reading looks like
0-5 volts from the wheel speed sensor, expected resistance of 1,000-2,000 ohms in wiring circuitry.
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 for signs of damage or corrosion. Repair as needed.
- 22. Measure the resistance of the wheel speed sensor to ensure it is within 1,000-2,000 ohms. If it's outside this range, replace the sensor.
- 33. Use a scan tool to monitor the sensor voltage while the vehicle is in motion. It should vary between 0-5 volts. If it's constant or zero, replace the sensor.
- 44. Clear the code and take a test drive. If the code reappears, inspect the wiring and connectors again for intermittent faults.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connectors
- Incorrect sensor resistance
- Corrosion or dirt on the sensor

Frequently asked questions
Is it safe to drive with this code?
It’s recommended not to drive until the issue is fixed since it affects braking systems.
Will this code come back after repairs?
If all faulty components are replaced and connections are fixed, the code should not return.
Why do I see this code with traction control issues?
This code often pairs with traction control problems because the system relies on accurate wheel speed data.
