Wheel Speed Sensor Circuit Failure
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 system can't get a proper speed reading from one of the wheels. This could be due to a faulty sensor or bad wiring. For example, if you're checking a sensor expected to read 0-12 volts while the vehicle is moving, and it shows 0 volts, that's an issue.
What the computer is actually seeing
The computer monitors the voltage signals from the wheel speed sensors, expecting them to vary as the vehicle moves. If it detects a reading that is constant (0 volts) or outside the expected range, it triggers this code.
What a healthy reading looks like
Wheel speed sensors typically output a variable voltage between 0-12 volts based on wheel speed; a functioning sensor should show a voltage change as the vehicle accelerates and decelerates.
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 connections at the wheel speed sensor for damage or corrosion. If found, repair or replace the damaged sections.
- 22. Test the voltage output at the wheel speed sensor connector with a multimeter. Expect a range of 0-12 volts while rotating the wheel. If it stays at 0 volts, the sensor itself may be faulty.
- 33. Inspect the sensor for any physical damage such as cracks or debris blocking it. Replace if damaged.
- 44. If the sensor checks out okay, trace the wiring back to the control module, checking for continuity and ensuring there are no shorts or breaks. Repair if necessary.
Common causes
- Faulty wheel speed sensor
- Damaged or corroded wiring
- Poor connector contact at the sensor or module
- Bad ground connection for the sensor or module

Frequently asked questions
Is it safe to drive with this code?
It's generally drivable, but without a working wheel speed sensor, features like ABS won't function, which affects safety in slippery conditions.
Will this code come back after clearing it?
If the underlying issue isn’t fixed, yes, this code will likely return after a short duration.
Why does this code appear with others?
Codes often pair with related faults, like issues with other wheel speed sensors or ABS system faults, since they share common circuits.
